(n.) One who "steals" kills, by either casting very powerful spells or simply by running up to an already engaged creature and killing it. Standard EQ combat etiquette states that when an NPC is already engaged by or engaging a PC, if the PC is not asking for help or in obvious immediate need of it (nearly dead, stunned, blinded, etc.) that any persons not already involved ask prior to engaging said NPC. Doing otherwise will get one branded as a "killstealer."
