Perform is the general skill describing the use of wind instruments, string instruments and percussion instruments, as well as skill at acting, comedy, dance, song, poetry and oration.
A Bard using Perform can perform the bardsong, which improves their allies' ability to fight in combat and withstand mind-affecting enemies. Perform is essential for any Bard who wants to have access to their bardsong.
Check: None required. The higher the rank in this skill, the better the bardsong.
Use: Select the skill to affect a 30-foot radius of allies around the singer.
All other classes can take Perform as a cross-class skill.
