Meta-Essence of theAnti-Essence

By drinking this black liquid, nothing will happen. However, if you combine it with another Essence (or a combination of Essences), it will turn into an Anti-Essence.

• If the original Essence gave you a power, the Anti-Essence will instead give you an anti-power that allows you to counter powers of the same type. (For example: if the original Essence would've allowed you to learn and cast magic spells, the Anti-Essence will allow you to learn and cast counterspells instead.)

• If you use an anti-power on a power of equal or lover strength, that power will be nullified; otherwise, it will merely be reduced.

• If the original power had to be activated to function, then the anti-power has the same requirement. Range, number of targets, cost of activation etc. stay the same.

• If the original power was a passive ability, then the anti-power will allow you to place “seals” on other people, which will negate/reduce their power. (For example: if the original Essence would've given you a healing factor, the Anti-Essence will give you the ability to place seals that negate the target's healing factor.) To place a seal on someone, you must touch your target. You can only place one seal per type, but you can dismiss already-existing seals at will.
