Objectives: You have to protect the area inside of the circle around the black rock. When you kill all of the monsters inside of the circle and you're standing in the circle with no monsters then it turns green and your meter at the top of your screen will fill up, your objective is to fill the meter completely by killing all monsters in the area. If all players within the circle die and there are monsters inside of the circle it will turn red and your meter will begin to diminish. The best way to do this event is have someone hit the monsters outside of the circle and hold aggro outside of it while someone else stands inside of the circle, this way the circle will be green at all times.
Objectives: When the enemies are wrapped in the purple balls you need to grab one of the giant crossbows in the fort and shoot them with the crossbow. When you hit them it will destroy the purple ball and you will be able to kill them. Protect the fort for the duration of the event, if you survive long enough you will complete the event.
Objectives: You have to grab the crystals and put them into the grinder before they turn into enemies. If a enemy spawns you can kill it, or if it's far enough away you can try avoiding it and continue with the event.
