Araevin, where you will most likely see a necro/bard, is with any big spawning guild. They peace mobs and wither, and it helps out the rest of the group, as they just stopped the mob in their tracks and opens up a window for large AOE attacks. If they go along with another necro, and double wither, it is amazing. You can solo or double team, almost every spawn. I personally dont ever want to build this template myself, but we have a guy in my guild that built it, and he is a very handy person to have at spawns.
