How do Soak/Trick or Treat/Forest's Curse work against a Terastallized Pokemon?

Question

I have three questions about terastal and soak/forest's curse/trick or treat: 1.if a pokémon is under the effects of forest's curse and terastalizes will the effects of forest's curse stop 2. Can you use forest's curse on a terastalized pokémon 3. Will either work as well for soak/trick-or-treat?

Comments

I'm pretty sure someone already asked a question about 2 and 3 but I can't find it

Does this answer your question? https://pokemondb.net/pokebase/413220/how-does-terastallizing-interact-with-type-changes

Terastalizing blocks the type loss from Burn Up and Double Shock, as well as ignoring Protean and Libero abilities that normally change the type of the user based on move usage.  I imagine that moves like Forest's Curse, Soak, and Trick-or-Treat would all fail, based on this information.

Thank you sumwun that helps answer my question:)

What questions do you still have?

Answer 1

If a Pokemon is under the effect of forest's curse and terestralises, the effect doesn't stop. The Pokemon becomes the tera type + grass.

You can't use forest's curse on a terestralised Pokemon. Terestralised Pokemon cannot have their type changed.

It should work the same for soak/trick or treat since they're the same move but with a different type.

I tested it in these replays, I hope it answers your questions completely.
