New Mechanic: Temporary Damage
What if you could inflict a sort of 'negative shield' onto your opponent? Temporary damage that would restore health back to your opponent after a certain time, but would still be completely lethal if your enemy ever drops below zero.
This would allow for some interesting spells, such as a balanced high damage finisher - that can really only be used as a finisher.
A couple edits:
-
It wouldn't have to be a skill with 100% 'grey damage', it could do part temporary and part real.
-
Another option (that I like a lot better) is a champion who after a basic combo could choose between: (a) A high damage finisher that does a bunch more 'grey damage' (b) A low damage trading option that 'procs' the temporary damage to make it stick.
I appreciate all the feedback!
