A Verbal that causes you to spend points against your will with no benefit in return. From the Accelerant core rules:
"Waste is always followed by either an attribute or a skill that has a limited number of uses. You lose one or more uses of the named skill or one or more points of the named attribute. Waste has no effect if you have no attribute points or skill uses left. If you do not have the named skill then Waste to that skill has no effect. As a default, Waste removes one point or use of a skill. If a number is placed before the attribute or skill name then you will lose more attribute points or uses of the skill. Skills that require attributes cannot be wasted directly and are unaffected by a Waste effect."
"Wasted attribute points and skill uses can be refreshed. A Cure Waste effect will restore points or skill uses lost to Waste effects unless they have already been refreshed or restored by some other means. Once a wasted attribute or skill use has been refreshed a Cure Waste effect will have no effect on you. Attributes and skills lost to a Waste effect are always refreshed before points lost through normal use."
"Waste can also be used to remove abilities of an empowered item. If the item has a unique name and Waste is followed by that name then any charged abilities of the item are removed as if they had been used."
