April 7* Raid Part 3: Inteleon (Ice Tera)

28th April - 30th, very glad to hear we’re getting another raid before the Iron Leaves/Walking Wake repeat.

Potential Pokémon from memory could be Annihilape, Crabominable, Abomasnow, Scizor, Forretress etc.

Maybe support Tinkaton?

Crits are going to be the gimmick so ability suppression may be key here as well. (For Sniper)

 

[Vengeance417]

Does Inteleon still have Focus Energy this gen? It had it in SwSh but Showdown claims it's no longer in its moveset. If it is, I can see a repeat of Samurott where it would have Focus Energy.

Does Inteleon still have Focus Energy this gen? It had it in SwSh but Showdown claims it's no longer in its moveset. If it is, I can see a repeat of Samurott where it would have Focus Energy.

It had it in SWSH because of the TR, and it wasn't added to the movepool in SV
So mercifully we're safe from that specific strategy. Looking at the movepool some things to keep in mind:
-Snipe Shot has a high crit ratio, and it says it ignores redirect moves & abilities....doest hat also ignore Storm Drain's absorption effect? Probably want Water Absorb instead
-Ice Beam, obviously, but we shouldn't ignore Blizzard. It also learns Snowscape! Feel like this one is a very strong possiblity.
-Icy Wind is there, can't ignore that if it decides to have pre-set spread attacks
-Air Cutter. Inteleon looking at Decidueye and rubbing its chin on spamming this
-It gets both Reflect & Light Screen. We've not seen someone do this kind of defensive set up, so something to keep in mind
-Taunt could happen eventually
-Dark Pulse, probably so you can't just plop Slowbro down. I mean you definitely will be able to, but you know how it goes.
-Haze seems like it could be nasty.
-I don't see it going Physical at all, but it does get Fell Stinger which seems like a more flavorful Sword Dance spam as a "finisher". Especially fi ti had AI routine set to use it if it sees a kill with it.

 

[Emergence]

Possible moves/strats:

• Cast Snowscape + Blizzard, like Typhlosion casting Sunny Day + Eruption
• Mist + Haze to prevent set up, Intelleon doesn’t have any notable boosters itself (besides Double Team which would be super annoying)
• coverage with Shadow Ball, Dark Pulse, or Air Slash/Air Cutter
• Tearful Look and Taunt could be annoying too, possible Icy Wind at the beginning like Samurott’s Bulldoze

 

[Vengeance417]

-Snipe Shot has a high crit ratio, and it says it ignores redirect moves & abilities....doest hat also ignore Storm Drain's absorption effect? Probably want Water Absorb instead

Snipe Shot only ignores the redirection aspect of moves and abilities, not the immunity part of the ability itself, so Gastrodon getting hit by Snipe Shot directly would still trigger Storm Drain. So yeah, Water Absorb is better.

I can see speed-control being a key support plan in this raid. Inteleon's naturally fast at 276, so many of our max HP max attacking stat mons will likely be slower than it without some investment.

A couple of theory-mon sets I have:


Samurott @ Shell Bell
Ability: Shell Armor
Tera Type: Fighting
EVs: 252 Atk / 220 SpD / 36 Spe
Adamant Nature
- Screech
- Swords Dance
- Bulldoze
- Brick Break

Shell Armor renders Samurott immune to Sniper crits, while providing Screech and Bulldoze support. 36 Speed will let you outrun Inteleon after one Bulldoze.


Polteageist @ Covert Cloak
Ability: Weak Armor
Tera Type: Ghost
EVs: 252 HP / 4 Def / 252 SpD
Calm Nature
IVs: 0 Atk
- Trick Room
- Skill Swap
- Light Screen
- Aromatic Mist

Despite the potential Dark Pulse, SpDef Polteageist will always survive a Sniper Crit from Modest 0 SpA, and Covert Cloak will prevent flinches or even that nasty Freeze chance from Blizzard or Ice Beam. Trick Room up and then give Inteleon Weak Armor. Hugely benefits your Iron Hands partners which will likely be a common sight.

 

[LPBvgc]

Ok, here is a wierd idea for a counter, but hear me out.


Kingambit @ Life Orb
Ability: Defiant
Tera Type: Steel
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Swords Dance
- Thunder Wave
- Iron Head
- Leer

Now, this may sound a bit odd, but this Kingambit set could work. It resists many of Inteleon's attacks, defiant lets it become stronger when hit by Icy Wind, it can cripple it with Thunder Wave (untill it clears it's statuses and stat drops), and hits Super Effectively with Iron Head. It will work ESPECIALLY well with Perrserker.

 

[R_N]

Shame alcremie isn't in the game yet

Decorate (+2 Attack & Special attack to target) support Alcremie + Assault Vest Iron Hands, the dream team!

 

[Vengeance417]

1x
Perrserker @ Choice Specs
Ability: Steely Spirit
Tera Type: Steel
EVs: 244 HP / 12 SpA / 252 SpD
Modest Nature
IVs: 0 Atk
- Steel Beam

3x
Perrserker @ Focus Sash
Ability: Steely Spirit
Tera Type: Steel
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
IVs: 0 Atk
- Fake Tears

12+ SpA Choice Specs Steely Spirit Perrserker with 3 extra Steely Spirits Steel Beam vs. -6 0 HP / 0 SpD Tera Ice Inteleon: 8448-9938 (100.2 - 117.8% of 30x hp boss) -- guaranteed OHKO

 

[Krockodile]

Here are some raid sets that might help against Tera-Ice Inteleon:

Set 1: Quaquaval:

Quaquaval @ Leftovers
Ability: Torrent
Tera Type: Fighting
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Brick Break
- Aqua Step
- Roost
- Swords Dance

I chose Quaquaval because it resists most of Inteleon's moves, with the exception of Mud Shot, Shadow Ball and Air Slash (the last one can be scary for Quaquaval). Aqua Step is used to outspeed Inteleon, which it only needs to do once. Swords Dance is used to increase its attack. I chose Brick Break because it can break Inteleon's Screens and doesn't have the drawbrack of lowering its defenses with close combat. Roost is used to keep it Healthy throughout the game. Torrent can be used over Moxie to give it a last-ditch effort to boost its Aqua Step damage.

Set 2: Tauros-Paldea-Fire

Tauros-Paldea-Blaze (M) @ Shell Bell
Ability: Anger Point
Tera Type: Fighting
EVs: 92 HP / 252 Atk / 164 Spe
Adamant Nature
- Body Press
- Tail Whip
- Sunny Day
- Bulk Up

I chose Blaze because I was thinking that Inteleon can use the same strategy as Samurott (which uses crit moves, allowing Tauros-B Anger Point to be a perfect counter). Sunny Day is used to weaken Inteleon's attacks, whilst Tail Whip is used to lower Inteleon's defense. Body Press is STAB move to attack Inteleon. Bulk Up is the second option if Inteleon is unable to deal a critical hit move against Tauros-B. 164 speed is used to outspeed Inteleon, leaving the rest to be invested in its attack and bulk. Shell Bell can allow Tauros-B to recover great amounts of health.

Set 3: Tauros-Paldea-Aqua

Tauros-Paldea-Aqua (M) @ Shell Bell
Ability: Anger Point
Tera Type: Fighting
EVs: 92 HP / 252 Atk / 164 Spe
Adamant Nature
- Bulk Up
- Body Press
- Tail Whip
- Raging Bull

This is similar to Tauros-Paldea-Blaze, except Aqua can resist Inteleon's Snipe Shot, allowing it to be a more bulky counter against Inteleon. Therefore, I consider it to be a more safer option compared to Tauros-Blaze. Raging Bull can be used to break down Inteleon's Reflect and Light Screen tactics.

Candidate 4: Revaroom

Revavroom @ Shell Bell
Ability: Filter
Tera Type: Steel
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Sunny Day
- Shift Gear
- Iron Head
- Taunt

Revaroom can resist most of Inteleon's special moves. The exception is Snipe Shot and Shadow Ball. The former can use be weakened by Sunny Day. Shift Gear + Iron Head, along with decent bulk and a good defensive typing can allow Revavroom to handle Inteleon by itself. Taunt can be used to stop Inteleon boosting up its speed with Agility, or using Light Screen/Reflect to take reduced damage.

After using Shift Gear, Revavroom is faster than Inteleon, so there's no need to invest in speed. Instead, Revavroom can have EVs invested in its attack and bulk.

The Next 2 mons are more niche, so be warned:

Candidate 5: Tatusgiri

Tatsugiri @ Shell Bell
Ability: Storm Drain
Tera Type: Fighting
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
- Tera Blast
- Nasty Plot
- Rapid Spin
- Helping Hand

Rapid Spin only needs to be used once to outspeed Inteleon. Nasty Plot + Tera Fighting can be used to deal super-effective damage against Inteleon. Storm Drain is used so that it can only be immune to Inteleon's Snipe Shot, but it can increase its own special attack. Helping Hand can be used to help other players if necessary.


Candidate 6: Toxicroak

Toxicroak @ Shell Bell
Ability: Dry Skin
Tera Type: Fighting
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Swords Dance
- Drain Punch
- Brick Break
- Low Sweep

Brick Break is used to stop Inteleon from setting up Light Screen and Reflect. Swords Dance is used + Drain Punch can be used for Toxicroak to recover large amounts of health, which is helped by Shell Bell. Low Sweep can be used to lower Inteleon's speed, allowing Toxicroak to move first instead and then recover health faster.

Dry Skin is preferred to allow Toxicroak to be immune to water attacks. However, I am not sure whether Toxicroak can handle Inteleon's other attacks. This includes Shadow Ball, Ice Beam, Blizzard and especially Air Slash.

 

[Worldie]

I think Snipe Shot / Ice Beam / Air Slash are a given. Luckily there's unlikely to be any crit-based shenenigan, however we should still not discount the variability of crits since Sniper is a thing regardless and with how many hits we'll be taking it's bound to happen at least once per 2 fights (moreso with Snipe Shot higher crit rate).

This is more of a reason to try to look for something that is not weak to water and possibly resists or immune it, to at least reduce the chance to be blasted into oblivion.
Obviously there is the option to go for Shell Armor mons, Cloyster, Samurott and Dreadnaw kinda come to mind, but they don't exactly provide a useful defensive profile outside of that, though the turtle can hit supereffectively with stab.

Snowscape + Blizzard is a potential candidate for turn 0, though I am a bit unsure to see this being the thing as it just doesn't "quite click" to me.

One thing I think may be vital is Sun however. If anything, cause it completely prevents Freezes, which are doomed to happen on anyone not using Covert Cloak or having direct fire coverage.

 

[Worldie]

So hear me out here

Scream Tail @ Leftovers / Shell Bell / Heat Rock
Ability: Protosynthesis
Tera Type: Water (optional)
EVs: 252 HP / 176 SpD / 80 Spe
Timid Nature
(hits 305 speed, 2 above 303 of +speed nature intelleon, can have 0 investment if boss is neutral nature, guarantees spdef under sun)
- Flamethrower
- Light Screen
- Calm Mind / Wish / Howl / Helping Hand / Noble Roar / Fake Tears / Psychic Fangs (if screener)
- Sunny Day

252 SpA Tera Ice Inteleon Snipe Shot vs. 252 HP / 176 SpD Scream Tail: 97-115 (22.3 - 26.4%) -- possible 5HKO after Leftovers recovery
252 SpA Tera Ice Inteleon Ice Beam vs. 252 HP / 176 SpD Scream Tail: 109-130 (25.1 - 29.9%) -- 0.1% chance to 4HKO after Leftovers recovery

Comfortably outspeeds and sets sun, proceeds to absolutely disregard any attack between the Proto boost and Light Screen, then you can either set up Calm Minds and chonk with flamethrower, or keep using supportive moves if you rather do that.

I'm confident it's Snowscape + Blizzard. Inteleon has no real other way to boost its Special Attack power, similar to Typhlosion and it spamming Sun-boosted Eruption. Ice Beam just doesn't do enough in comparison. Thankfully, Blizzard doesn't get boosted with Snow, but the kicker is that Sniper crits from Blizzard, while not going to be common without Focus Energy, would be unholy, along with the potential Freeze chance. Plus, Snowscape would provide Inteleon with +1 Defense, mitigating its low natural bulk against the myriad of Iron Hands that are gonna pull up to this raid.

Does Snow’s +1 work on tera-ice Pokémon?

But also I agree Blizzard will be its spread move. I wonder if they’ll go mixed with it? (Acrobatics or maybe Ice Shard?)

 

[Vengeance417]

Yes, it does.

I doubt it's going to be mixed if it doesn't at the very least use Swords Dance as one of its special moves. At least with Typhlosion, it has high BP moves with Earthquake and Play Rough, but Inteleon's best physical options are Liquidation and 110BP Acrobatics, with the latter still being outdamaged by Air Slash.

At the same time, I also doubted Typhlosion going mixed and was proven wrong, so we'll have to wait and see lol

28th April - 30th, very glad to hear we’re getting another raid before the Iron Leaves/Walking Wake repeat.

Potential Pokémon from memory could be Annihilape, Crabominable, Abomasnow, Scizor, Forretress etc.

Maybe support Tinkaton?

Two words, Anger point.
On who specifically? Tauros-Paldea-Blaze.
It's definitely going to have Snipe Shot in its moveset, and other stuff which I dont think will be super effective against Tauros. This is solely if it specs into Special.

Eh? Do you not mean the Aqua breed? Blaze Breed will take a lot from Snipe Shot?

But that’s actually a fair choice for an offensive Pokémon, but if it carries Air Slash then probably not.

 

[Worldie]

I'm doubting of any "relevant" phisical move.

While it goes get some options (Liquidation, Acrobatics, Sucker Punch) that's kinda really it. They don't really add any coverage over just using the special variants, and so far the only times they've gone for split attacks is when they actually either added coverage or had significantly higher BP.

It doesn't even get any grass or electric attack to do some trolling with Soak..

However what I did notice is that it does get Air Cutter and i'm actually thinking it'll be in the moveset instead of Air Slash, may even be a double attack scenario like Decidueye.

Re Tauros Paldea:

negative. You don't want to be eating crits from this guy. This actually hurts.

0 SpA Sniper Tera Ice Inteleon Air Cutter vs. 252 HP / 252 SpD Tauros-Paldea-Aqua on a critical hit: 237-279 (66.9 - 78.8%) -- guaranteed 2HKO
0 SpA Sniper Tera Ice Inteleon Air Slash vs. 252 HP / 252 SpD Tauros-Paldea-Aqua on a critical hit: 291-345 (82.2 - 97.4%) -- guaranteed 2HKO

Nevermind Snipe shot on the fire version
0 SpA Sniper Tera Ice Inteleon Snipe Shot vs. 252 HP / 252 SpD Tauros-Paldea-Blaze on a critical hit: 468-552 (132.2 - 155.9%) -- guaranteed OHKO

Remember Tauros-P special bulk is actually quite lacking, you're looking at 75/70

And you don't even 1hko at full, assuming you actually survive 2 hits to tell the tale as you have to fully invest in bulk to even think of living 1 hit in first place
+6 4 Atk Tauros-Paldea-Blaze Close Combat vs. 0 HP / 0 Def Tera Ice Inteleon: 1596-1878 (567.9 - 668.3%) -- guaranteed OHKO

 

[Vengeance417]

A couple more theories:


Toxapex @ Covert Cloak / Poison Barb
Ability: Merciless
Tera Type: Poison
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk
- Acid Spray
- Sludge Bomb
- Recover
- Venoshock

A fun little offensive support Toxapex that I made up. You wouldn't want this Pokemon to be the main damage dealer, but as a partner to other special attackers that take advantage of your Acid Sprays. Unlike most support Acid Spray mons, though, you have the ability to actually chip in vs the shield. Sludge Bomb helps proc Poison through the shield, then you can take advantage of Merciless providing autocrits for your 130 BP Venoshock. Covert Cloak will prevent you from getting flinched down by Air Slash or frozen by Blizzard / Ice Beam, but if you want more power, Poison Barb works, too.

Calcs

Offensive:

252+ SpA Toxapex Venoshock (130 BP) vs. -6 0 HP / 0 SpD Tera Ice Inteleon on a critical hit: 1147-1351 (13.6 - 16% of 30x hp boss) -- 1.1% chance to 4HKO after poison damage

0+ SpA Sniper Tera Ice Inteleon Blizzard vs. 252 HP / 4 SpD Tera Poison Toxapex through Def Cheer on a critical hit: 177-208 (58.2 - 68.4%) -- guaranteed 2HKO

Clawitzer @ Covert Cloak
Ability: Mega Launcher
Tera Type: Water
EVs: 252 HP / 4 Def / 252 SpD
Calm Nature
IVs: 0 Atk
- Mud-Slap
- Heal Pulse
- Helping Hand
- Entrainment / Icy Wind / Mud Shot

A sturdy support that has Mega Launcher-boosted Heal Pulse. Entrainment can be cool t1 to remove Sniper, but would be kinda bad if it has Dark Pulse. Otherwise, Icy Wind or Mud Shot can be used for speed-control.

 

[Terimas]

I would say that the Covert Cloak is likely going to be the mandatory item choice for this raid. Blizzard spam is going to be very likely, and Air Slash will also likely be in play. It's very easy for RNG to get out of control with Freeze, flinching and critical hits being involved.

Freeze and flinching can at least be nullified with Covert Cloak which should help staying alive.

 

[Original Dragon Arkvelza]

Shell Bell
Mirror Armor (Just in case of things like Icy Wind or Low Sweep)
Tera Steel
252 Sp Def/252 Atk/4 HP
Adamant

Iron Head
Screech
Tailwind/Scary Face/Sand Attack
Roost

I'm sure people will try Iron Def Body Press, but even with Corviknight's very high Def the stab from Iron Head is enough to outdamage it, even with a Def nature, a min roll on Iron Head, and max roll on Body Press. You could go Tera Fighting to make it stronger, but why go through that much effort when 1: You'll need to wait some turns before you can terastallize and 2: Tera Steel Iron Head will do even more damage thanks to the bonus stab.

+6 252 Atk Corviknight Iron Head vs. 0 HP / 0 Def Tera Ice Inteleon: 1130-1332 (402.1 - 474%) -- guaranteed OHKO
+6 252+ Def Corviknight Body Press vs. 0 HP / 0 Def Tera Ice Inteleon: 934-1100 (332.3 - 391.4%) -- guaranteed OHKO

Also, the reason I chose Shell Bell rather than Covert Cloak is because you're really gonna need that healing in the case of Snipe Shot critting, though thankfully without Focus Energy it shouldn't happen too much compared to Samurott. Also, despite Corviknight's very low speed -1 is enough to outspeed unless it's a speed nature. And in that case, Tailwind allows you to outspeed, though it's very short lived, but at least it's not affected by Inteleon removing buffs/debuffs.

 

[Vengeance417]

Flutter Mane @ Shell Bell / Covert Cloak
Ability: Protosynthesis
Tera Type: Water
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
IVs: 0 Atk
- Fake Tears
- Calm Mind
- Sunny Day
- Mystical Fire

Sunny Day weakens Snipe Shot, activates Protosynthesis and boosts your SpDef, and removes the possibility of getting Frozen. Fake Tears and CM for boosted damage. Mystical Fire not only gets boosted by Sun, but lowers Inteleon's SpA. Tera Fire is unnecessary and not smart, so I went with Tera Water to resist both STABs.

The best part is that Calm Flutter Mane is naturally faster than Timid Inteleon if it ends up running that nature, so you'll always be able to drop Inteleon's SpA before it gets to act (unless Icy Wind is involved, in which case, I'd use Covert Cloak instead of Shell Bell).

Defensive calcs

0+ SpA Sniper Tera Ice Inteleon Blizzard vs. 252 HP / 252+ SpD Protosynthesis Flutter Mane on a critical hit: 162-190 (51.5 - 60.5%) -- guaranteed 2HKO

0+ SpA Sniper Tera Ice Inteleon Snipe Shot vs. 252 HP / 252+ SpD Protosynthesis Flutter Mane in Sun on a critical hit: 58-69 (18.4 - 21.9%) -- possible 5HKO

 

[Wolfencrest129]

Could Calm Mind/Stored Power Vaporeon be viable as a solo option?

Vaporeon@ Shell Bell / Covert Cloak
Ability: Water Absorb
Tera Type: Water
EVs: 4HP / 252 SpA / 252 SpD
Modest Nature
IVs: 0 Atk
Aqua Ring/Rain Dance
Calm Mind
Acid Armor
Stored Power

Vaporeon's naturally high HP and decent SpDef would be good for dealing with the moves it'd be neutral to, and it's naturally resistant to Ice. Water Absorb to heal off Snipe Shot, Aqua Ring/Leftovers for extra longevity, Rain Dance for removing Snowscape, and potentially lots of damage from Stored Power. It's only issues would be if there's physical moves, and it's slower than Intelleon.

There's 2 main problems with Vaporeon

1) as you said, it's slower, meaning you will definitely have to eat hits (potentially, sniper crits which disregard the Calm Mind Boosts), and if one of the coverage happens to be Air Slash, that's also eating flinches (forcing covert cloak)

2) you are not hitting supereffectively and don't even have Stab, meaning you will likely struggle to actually 1hko. Stored Power worked on Cinderace / Greninja cause they were actually weak to it
+6 4+ SpA Vaporeon Stored Power (260 BP) vs. 0 HP / 4 SpD Tera Ice Inteleon: 1255-1477 (446.6 - 525.6%) -- guaranteed OHKO
You will need multiple hits of this to actually kill, and this assumes you even get to 6 in first place
Meanwhile you have to eat potentials of
0 SpA Sniper Tera Ice Inteleon Air Slash vs. 4 HP / 252 SpD Vaporeon on a critical hit: 121-144 (30 - 35.8%) -- guaranteed 4HKO after Leftovers recovery (or aqua ring)
as well as just eat hits while setting up and notbeing at +6 yet, or whenever the buff wipe happens

I don't think you'd really have the time to set up AND beat the raid, even with Tera Psychic.

If Inteleon isn't packing Dark Pulse, I think Slowking would be the better Stored Power user thanks to STAB and access to Amnesia, Nasty Plot, and Slack Off. Hell, Dark Pulse doesn't even do a lot; just need to worry about flinching and Sniper crits.

0+ SpA Tera Ice Inteleon Dark Pulse vs. 4 HP / 252 SpD Slowking: 114-136 (34.3 - 40.9%) -- guaranteed 3HKO

0+ SpA Tera Ice Inteleon Dark Pulse vs. +2 4 HP / 252 SpD Slowking: 58-70 (17.4 - 21%) -- possible 5HKO

0+ SpA Sniper Tera Ice Inteleon Dark Pulse vs. 4 HP / 252 SpD Slowking on a critical hit: 258-306 (77.7 - 92.1%) -- guaranteed 2HKO
