1. Queue to the arena
2. When its your turn and you get ported inside, shadowstep to a player or npc to get out. The faster i do it, the higher chance it bugs out.
3. You will be removed from the arena and queue. Your opponent npc will do his /yells, summon his adds or whatever depending on the fight.
4. The NPC will despawn.
4. Now one of two things will happen.
a) Next person in queue gets inside
b) Nobody will be able to join, and after 2mins the enrage rain of fire will start.
Regardless of what happens it can bug out or not.
5. Next person will join. Depending on how many players are there and what you wanna do with the bug, either queue up or watch the carnage.
6. 5-15seconds after the player joined, you or others will be able to join him. This can and will happen multiple times. Each time a new player joins, they will also summon an npc.
7. If one of the npcs die, all players will be awarded a win and get ported out.
You can use this to skip bosses you are stuck on, help others or just bug everything out.
Bonus: When you reach rank 8, one of the 4 rare bosses adds will not despawn unless somebody defeats their npc inside. The boss i am talking about is the cthun eye boss. His adds will be harmless unless killed. If they die each add will start attacking a random place on the ground for 250000dmg. This ground attack will be invisible for people who were not present when the adds were summoned/killed. This makes it really hard for people to kill their boss.
Please post if you find other ways than shadowstep to bug it out. One theory i have is that you log off just as you get ported inside.
