WOW PowerLeveling: It’s a good idea to have the healer cast Mark of Protection on him
Player Guide - build: You will hear the term "build" a great deal in relation to character skill selection in Guild Wars, especially in PvP play.
Your character build refers to the specific assortment of skills and attributes that you have selected for a particular mission or WOW PowerLeveling quest. Many players tend to settle into a preferred build, while others like to adjust skills for every new enemy.
The skills in a solid character build should work well together, and work well against the foes you expect to encounter. You should also take into account the other members of your group - it's a good idea to confer with the other players in your party so that there's a minimum of skill overlap.
For example, if there are two Monks in the party, one may choose to set up as the healer for the group with skills linked to the Healing Prayers attribute, while the second acts as the party's protector, choosing a selection of skills tied to Protection Prayers.
It’s a good idea to have the healer cast Mark of Protection on him if things get rough, since if he dies, all your effort is shot. Once you survive the boss that comes along with one of the waves, it’s a rather simple waiting and killing game.
