Type: Anarchic
Source: Dragon #326
The power of chaos improves your bardic music ability. Your performance becomes frenetic and completely discordant. Something about it speaks to some forgotten aspect of your primal consciousness.
Prerequisite: Perform 4 ranks, bardic music ability.
Benefit: Your effective bard level increases by +4 for the purposes of determining which bardic music abilities you can use. This feat can't increase your effective bard level beyond your Hit Dice. However, if you can't benefit from the full bonus immediately, but you later gain non-bard Hit Dice, you may apply the rest of the bonus.
For example, a human 5th-level bard/3rd-level fighter who selects this feat would increase his effective bard level from 5th to 8th (since he has 8 HD), allowing him to use the suggestion ability and increasing his inspire courage bonus to +2. If he later gained another non-bard level, he would gain the remainder of the bonus and his effective bard level for bardic music abilities would become 9th (since he now has 9 HD).
This does not affect your spells per day or spells known. It only increases your effective bard level in regards to using your bardic music ability.
Special: Aura of Chaos: A character with at least one anarchic feat radiates an aura of chaos with a power equal to his character level (see the detect chaos spell), as if he were a cleric of a chaotic deity.
