Sometimes in battles, the opponents use stuff that lasts a few turns. Like healing themselves, or doing damage on my pets. I was wondering if you yourself can get those things to use? And if you can, how?^^

Some stuff they do, like Regeneration, is stuff our pets can't do yet (I guess it's in the proficiency tree, but at a really high level that we can't even reach at the moment because our levels are capped at 60).

But some attacks in the proficiency tree can cause ailments. Such as Slash (in the air tree) can cause bleeding or something like that. o:
