Which talent grid should i follow? Here is what i had in mind, separating between offense and defense to give her a chance to kill minions in one hit and survivability to fire her special as many times as possible
What you have planned out will work well, since she has high defense she’ll be able to take a lot of hits while getting maximum benefit to her attack stat.
I wouldn’t do the 20th node though, too expensive for the mana boost. +19 is the highest I’d go
