I tried using the sleeptalk set on Milotic where you rest and sleeptalk as your primary moves. It's suppose to synergize with the ability Marvel Scale (in theory) to get an increase in Defense. I use rest and Marvel Scale does not activate. Is there a bug or am I doing something wrong?

marvel scale is Ups Defense if there is a status problem. so it will be activated if there is status problem

However, using Rest inflicts sleep which is a status problem so, shouldn't it boosts her defense?

idk..what status discrease or low if u use rest??

I have noticed this also, i really think this needs to be tweaked as it is technically a status problem.

the rest is The user goes to sleep for two turns. It fully restores the user’s HP and heals any status problem...so I know is if u have status problem it will refresh and back to normal status so there will be no status problem that's why its not or maybe I'm wrong with this..

a status problem afaik is poison, paralyze, and burn. However rest cures all status effects and puts the user to sleep.

Nono. When you use rest, you are inflicted with a Sleep status. B/c you are inflicted with a status, your defense should technically go up.

 

I'm not sure whether if sleep is the only status that causes it to not work. Did not test for paralysis or burn etc

maybe yes if the opponent make u sleep but the move rest is refresh the status and health..so no more status problem..
