Mechanics guide
This sim trains the raid mechanics of Ulgrax the Devourer, the first boss of Nerub-ar Palace in World of Warcraft: The War Within. It also teaches WoW's visual raid language: swirls mean move out, blue bubbles mean stand in.
- Swirlies: swirling ground circles mark incoming damage. Move out before they burst.
- Webs: sticky web patches cover the arena and slow anyone standing in them. Path around them.
- Digestive Acid: a baited circle lands on you, then bursts after a delay. Run it out to the edge, and note that the blast dissolves webs caught inside it.
- Carnivorous Contest: a blue soak bubble appears. Run INTO it with your allies before the timer ends. Soaking together splits the damage; missing the soak is a hit.
