Guild Thief

The Guild Thief is a special NPC mercenary in a Guild vs. Guild match. He has the ability to open locked gates to the opponent team's base.

To get the guild thief to follow you, simply talk to him. He will follow whoever talked to him first until he is released by the same player talking to him again. Once that is done, he will follow another player.

To have him unlock a gate, the player he is following must simply interact with the gate lever. The thief will then begin to unlock the gate.
