The time and actions occuring between the moment the mob is aggroed and the time it reaches its destination are collectively known as the pull. A player who executes a pull is known as a puller. A pull that does not go according to plan, and puts one or more player characters in danger as a result, is known as a bad pull. Bad pulls often lead to wipes, and sometimes to training. Crowd control abilities and emergency abilities can make it easier to survive a bad pull. Pulling can be contrasted with fighting at spawn, the other most common tactic for initiating combat.
