Death Blow

(Complete Adventurer, page 106, DnD 3.5)

[General]

You waste no time in dealing with downed foes.

Prerequisite

Improved Initiative, base attack bonus +2

Benefit

You can perform a coup de grace attack against a helpless defender as a standard action. Doing this still provokes attacks of opportunity as normal.

Normal

Performing a coup de grace is a full-round action.
