Clivet is a member of the Cult of Hazeel. While doing the Hazeel Cult quest a player must talk to him to choose sides. Should a player choose Hazeel's side, they would get a Mark of Hazeel. Though he's level 13, he's immune to poison.

However, if they choose the Carnillean side then Clivet flees on a raft in the sewers and they must manipulate the sewer valves to get to him.

As of 27th of January 2009, players who have finished Hazeel Cult taking Hazeel's side but then have lost the Mark of Hazeel, can get it back by talking to him.
