Trope Workshop:Power Buff

MOD: How is this different from Status Buff? Please see the conversation on the talk page.

A Power Buff is a superpower that increases characters' abilities and even other's superpowers. Individuals who possess this power can increase their and others' physical abilities beyond their innate limits. When it comes to superpowers, it gives a stronger output. These effects are usually temporary, especially if range is involved. Boosting superpowers too much may also entail other Necessary Drawback like making others' powers uncontrollable, inducing Power Incontinence.

Inversion/opposite of Power Limiter, which limits a person's power. Contrast Super Empowering, which is about giving a person who didn't originally have powers some, although it's not impossible for a granter of powers to also alter its gifts.

The trope in the form of items is Amplifier Artifact.

Examples of Power Buff include:
