Acquisition
Signet of Capture:
 * Robah Hardback (Floodplain of Mahnkelon)

Trivia

 * Before Nightfall's official release, this skill was called Destructive Chop.
 * It is possible that this skill's icon is that of Kanaxai. This is unlikely, however, considering the design of the axe and the build of the body of the creture portrayed.
