When living, he trains Marksman at the Apprentice level. Shameer will sometimes interfere with the "Paranoia" quest, by repeatedly sneaking up on and attempting to rob the first target of the quest while he is resting from his farm duties.
Shameer is usually killed by a swarm of guards after too many failed pickpocketing attempts. Often it can appear as though Shameer and the target are meeting, especially since the target will say "Must we speak this way?" when they begin the conversation.
This is because Shameer is apparently on poor terms with the other townsfolk when the Hero arrives, and when he attempts to rob a person from the front, it enters a conversation instead.
