Dragon Yapper
Source Monster Codex pg. 128
Kobolds’ yammering songs distract opponents in combat, hindering their ability to attack.Bardic Performance: A dragon yapper gains the following types of bardic performance.
Yapping Song (Su): A dragon yapper can use performance to annoy those that hear it, causing them to take a –1 penalty on attack and damage rolls (minimum 1) and a –1 penalty on saves against fear effects and charm effects as long as the dragon yapper continues performing. This penalty increases by 1 at 5th level and every 6 levels thereafter. Yapping song is a mind-affecting ability that uses audible components, but is not language-dependent. This performance replaces fascinate.
While I believe the answer is yes (by RAW and just mechanically), does this ability hit allies? And also by extension, you?
