@VinnyLam We don't really know. I would imagine those powers are just theirs and not his. To me it seemed like all he did was give them power, which awaken their abilties/kept them alive.

And when they did die he got his power back plus whatever they gained in terms of power plus their lifes (think of it like whoever thought they killed them was actually just breaking the jar for there life to go to Yhack(hoeever it is spelled). And he may get there knowledge and exp to.
