About Aversa builds

The thing is that she need a lot of hp to debuff enemies and the A slot is the place to boost her HP.
Imo a tactic skill can cover those effects much better.

they would be more helpful if her hp was naturally higher. If you dont care about her effecting all units, i say go for it, but if you want her tome to really shine, you gotta use her A and seal for hp. I suggest having her teammates buff her instead of boosts
