I checked if Terrain Pulse's type can be changed with an Ability that changes types of moves.
I was so unsure about this if it's the same behavior with other moves that can change types purely due to their effects. So, I decided to investigate. Had an Exeggutor with Terrain Pulse and Skill Swap, an Amaura with Refrigerate, and Cursola.
The plan for the test:
- Send out Exeggutor and Amaura.
- Have Exeggutor use Skill Swap on Amaura, so Exeggutor can get Refrigerate.
- Switch out Amaura for Cursola.
- Have Exeggutor use Terrain Pulse on Cursola.
The result? Terrain Pulse was
ineffective on Cursola. Because of this,
Terrain Pulse is unaffected by means like Refrigerate.
