if a pet has 2 or more 'may cast' talents, is the chance of each or one of the 'may cast' talent lowered? and can a pet do 2 or more auto casts consecutively (3 or more spells casted from one player in total in one round)?
Each may cast is a unique roll of the dice and any one of them may go off whenever a trigger happens in battle.
I have an owl that has may cast Fairy, Unicorn, and Tower Shield. All three of these talents are triggered by damage done to me or anyone else on my team. Also, the heals can be triggered by others' healing, including another pet, a mob, or someone on my team.
So, if my teammate gets hit, my owl may interrupt to cast a Unicorn on us both. If my teammate's pet casts a Sprite, my owl may also cast a Fairy on me. If an enemy hits me, my owl might cast a Tower Shield and then a Fairy. If an enemy hits someone on my team, my owl still might interrupt to put a Tower shield on me.
Because any healing can trigger a 'may cast heal,' I've had pets with 'may cast Spritely' trigger and cast that spell on me three times within the same turn. It's rare, but it does happen.
