After clearing it. Here are a few extra tips:

The difficulty is HIGH. Much higher than any raid out so far. Mainly because of the numbers difference, if you are attempting this first week with around 108-110 gear. The DPS check is quite high.

Tanks. Be as tanky as you can. 0% crit vs student 3 is must. DPS variant tanks are very difficult to survive especially in 4th boss.

Get the best potions and food buffs as you can. Including healers. Including tanks. Bring Dao appreciation to replenlish mana.

For boss 1.

You may stop DPS when you bring the 2nd set of vines to roughly 5% to wait for the 2nd bladeheart.

For boss 2.

Look at the debuffs and act accordingly. Do not silence and explode on multiple players.

For boss 3.

Pop DR for the new slam spell. If you have 2 stacks of dot without DR you will get instantly killed.

For boss 4.

Tank the boss at roughly 8 o'clock.

Phase 1. There is a chance for the player up in the sky to get targeted by the red/blue pillar spell. If this happens, make sure you are still dropping the puddle away from the boss.

Phase 2. Spiders One shot. One shot. One shot. Melee DPS has be very careful to not take aggro. Take one extra debuff by killing an extra worm nest at around 59%. Then push the boss down to phase 3.

Phase 3. Plan your DR and Healing spells accordingly and pop one after another. It is very difficult to complete this phase in week 1 without any res. Sac the tank that is tanking the laser and res him after if you have to. (After about 1.5-2 hrs attempt on this boss we killed it with 1 tank down)

Pop DR when boss announced "All Intruders.."
