roamer  

ZAM Network Wikibase™ All Games

A Roamer is a mob that moves around, usually along a set path. The path could be short and easy to spot, or could be very large and seem almost random. Roamers are most dangerous when they move through an area where you are already engaged in another fight, adding to the encounter and, quite easily, resulting in a wipe.

It is very important for the Main Tank to identify roamers early and, if possible, pull them first to reduce the danger that they will add later.
