By drinking of this Essence, you've gained the power to steal abilities from others!
*You can steal and use abilities from anyone, no matter how unique or metaphysically tied to those people the powers are.
*You will never suffer any ill effects from using these powers, either. Or, more accurately, lasting ill effects. You can use the Mangekyo Sharingan without fear of going blind, but it'll still hurt like hell, and tire you out rather quickly.
*You can "forget" abilities if you so wish, causing you to no longer be able to use them. If you want to use those abilities again, you'll have to hunt down the original user.
*The original user of the ability retains full use and skill with their ability.
*The exact mechanics of this are left up to the user. It can be anything from requiring a touch to just needing to look at the target.
*You gain a sizable store of any energy that these abilities require, and it regenerates over time.
