Hello, I am a lvl 51 storm wizard in the grotto. Should I wait to level up?
It all depends on your play style, gear and deck set up and how you are doing - can you defeat things or are you being defeated a lot? Personally I find the higher the level you can be for this area the better because it can be a test of your wizard.
You should try and see how you do there and i am at the same part and lvl 50 and doing good there ( and the best way to beat the bosses is with a stronger wizard
