Steps:
So I was tanking Hullbreaker Isle and the monkey that guards the bridge just came across and kill my party. We could not target him and he was doing a lot of damage to us and ended up killing us. See screen shoot to see it. I pulled the group of mobs next to the bridge and then ran onto the bridge to pull the 2 monkeys then provoke the bird near the end of the bridge and then ran back to the start of the bridge so we could kill them all.
