Sentinel
 

Level 8 enchanter spell. When cast on a location, it triggers when any npc gets close to the spot it was set. The spell sends a message back to the caster that "a !#@$ has triggered your sentinel". This has been a passive trigger and works anywhere in the zone. I have found that the trigger response of the spell now agros the mob to the caster. I believe this is a bug. The trigger of the spell should not agro.
