Perform

Perform (Cha)
The perform skill represents the ability to entertain via a performance. Unlike PnP D&D, in DDO there is a single perform skill. Bardic Music requires ranks of perform in order to be able to use it, for example 3 or more ranks in perform is required for a Bard to use the Fascinate song ability. A high perform check also increases the DC of the Will save vs. being fascinated (confirmed?).

It is highly recommended that bards keep their perform skill maximized. There seems to be no use for this skill for other classes.
