|Amp Skill Info|
|Cast Delay:||3 seconds|
Cancels active Performance Skills the caster is performing. In an Ensemble skill, only the player that started the ensemble can cast Amp. Cannot be used in the 5 first or 5 last seconds of the duration.
- It is also common to hotkey both the Instrument/Whip along with a Dagger type weapon which performs the same function as Amp but ignores the 5 second song delay and without the associated cast delay following its usage.
