Also, based on my googling, it seems my main damage will come from Hex and Eldritch Blast. And luckily Eldritch blast, like all cantrips, scale off of character level and not levels in a particular class. So I'll be able to get 3 Eldritch Blasts per turn in 1.0 even if I multiclass. Also aware this is pretty late game build because if I wait til I get 5th level spells in Warlock, I won't get Metamagic from Sorcerer until level 12, the max in 1.0
