In light of the recent Sorcerer nerf w/ Draconic Bloodline + Scorching ray I went in search of a damage boost. I figure Twinned Spell (PHB, p. 102) + Hex (PHB, p. 251) is a good combo.
(Note that Hex can only target a single creature at any level, so it should work with Twinned Spell.)
My plan is to target both on one guy when casting, then I spend two bonus action, over two turns, moving each Hex over to the BBEG.
Does this work? Can I move Twinned Hexes onto a single creature?
Addendum: What would the effects be of a Twinned Enhanced Ability, targeting different attributes given that spells don't stack.
