Signet of Capture

Usage
With the Signet of Capture you can learn new skills from a dead enemy boss.

You can only capture skills of your current primary or secondary profession.

To use the Signet of Capture, defeat a boss and activate the signet while standing near its corpse. A dialog box will appear that lists all dead bosses of your primary or secondary profession within range. For each boss listed, it will list all the skills this boss has that are capturable -- Elite Skills and regular skills, as opposed to Monster skills. Click on the one you wish to capture, confirm, and the signet will be replaced by that skill. If you see nothing you like you can cancel the capture and keep the signet for a different boss.

You can have more than one Signet of Capture at a time in your Skill Inventory and you can equip more than one Signet of Capture in your Skill Bar at a time. Once a skill is captured, that Signet of Capture will be permanently replaced by the captured skill in your skills inventory. If you had more than one Signet of Capture equipped, the others remain in your skill bar. It is possible to have multiple elites in this fashion, although all but the one placed earliest in the skillbar will vanish upon rezoning.

Acquisition
Prophecies Campaign: To introduce you to the Signet of Capture, Magi Malaquire in Lion's Arch gives you the quest Malaquire's Test and one Signet of Capture upfront, and another one as part of the reward.

Whether or not you complete Malaquire's Test, you can purchase additional signets from most other skill trainers in Kryta, Maguuma Jungle, the Crystal Desert and the Southern Shiverpeaks. If your Guild Hall has a skill trainer, he will sell Signet of Capture to any PvE characters.

Buying a Signet of Capture will cost one Skill Point and some gold.
