new job - vampire

[Shougun]

OP lol if you don't mind in a few weeks I might revive the topic with a different title XD. I'm interested in the idea . Also wont stop posting here but just after it's passed the main page some time later I figured I could make a thread on it as well (rather than bump).

Doesn't Dark Knight have a thing where they can heal themselves by dealing damage?

*Swaps to Dark Knight and checks hotbar tooltips*

Yes, yes they do.

The whole concept of healing yourself by hitting the other guy is at least semi-vampiric in nature, though it's using DARKNESS! to simulate the effect rather than being an actual vampire.

Work from that angle, use the idea behind the Dark Knight and apply it to ranged weapon user, watch the DARKNESS! powered guns wreck folks.
Same power source, drastically different playstyle.

OP is refering to Vincent's chaos materia ability, in FF7 his limit break turns him into neat demon like monsters and in FF Dirge of Cerebrus you get to see him in chaos form:





^ Vincent (as you may recall he is this way from experiments by Hojo, that nice guy who made Sephiroth and Cloud who they are - really nice guy, good fam man :P).

So a bit like darkness power you reference I guess but a key point of the OP is not blood sucking but rather transformation.
