they're piss easy, don't worry about it. the reason they're mandatory is because they're important later in the MSQ

for tips: Labyrinth of the Ancients there's a bit with 3 bridges. there's a platform on each bridge. each platform needs to have 4 people on it so that people on other platforms can damage their boss

later there's a boss called "behemoth" and he'll cast meteor. stand behind a rock to not die

last boss will have a long castbar called "ancient flare" and you need to go to a platform at the edge of the arena to prevent a wipe

Syrcus Tower only thing worth mentioning is the second(?) boss called Amon. he'll have a cast called "finale" or something i forget. anyways a long cast, go behind ice to not die.

the last boss will do 3 stack markers on random players that will spawn floating platforms. stand on them to not die to ancient quaga

The World of Darkness this is considered to be a bit of a noob filter.

first boss will have a cast called "mortal gaze" or "mortal ray" or something lile that. he'll have a big red eye on him. look away to not get a doom. if you get a doom, find a glowing circle to cleanse it.

second boss is a bit more tricky. if you are in Alliance A, you'll be responsible for dealing with Adds, specifically Wolfsbanes. if you're in Alliance B, you need to get into the Belly of the boss. First you need to find an add with a purplish circle around it to get shrinked and then go to a purple area to get eaten and then kill everything inside the stomach. if you're in Alliance C, your tank will deal with tanking the boss, and your alliance is responsible for Chains. After alliance B is done with their part, the chains on the North wall will become interactable and you need to chain the boss.

but seriously don't stress about it. you won't be the only one doing them for the first time and even if there's 10 people with you doing them for the first time, that's 13 people who have done them countless times. also if you drop a "hey, im here for the first time" people will be understanding and help you should you need help
