bleeding attack feat

[vhok]

does the bleeding attack feat instantly deal 1d4 bleed or does it do ongoing bleed damage?

Your unarmed strikes cause your opponent to bleed.

Prerequisites: Improved Unarmed Strike.

Benefit: When you damage an opponent with an unarmed strike, you deal an extra 1d4 bleed damage.

Special: This ability does not stack with other special abilities, attacks, or items that allow you to deal bleed damage

It takes it at the beginning of its turn, unless the ability states otherwise. Look at the entry for Bleed on pg. 565 of the CRB.

The name of the feat is Belier's Bite, btw.
