Mega necro. But sure! The guy in the entrance gives you a wolf and boar whistle. Go to the respective wings for boar/wolf and target a trash mob and use the respective whistle. You turn into one of the mobs and then can go to the main mob at the end of the wing and attack one of 3 primordial shacklers. It then comes for you, kill it. Repeat for each shackler then kill the main mob. Repeat process for the other side. Then, go up to the top platform and then the dragoon will send waves of mobs at you. Survive that then the name himself will spawn. Kill him. Then you win and get cookies.
