Cheat Sheet for bosses we haven't gotten to yet.

Festergut

• Putricide joins the fight and throws Malleable Goo at the raid.   Same Malleable Goo in his fight, chucks slime, explodes, slows you.   Can no longer have ranged stacked up on melee.   More spreading out so more areas he can target.    Tanks and healers try not to get hit either.

Rotface

• Putricide joins and does Vile Gas to ranged people only.    So can't have everyone stacking anymore.  Keep at least 2 ranged and the kiter out.
• Infection does more damage, and is a 75% healing reduction debuff
• Ooze Flood is a stacking 10% slow (and damage), stacks to 10

Putricide

• Both oozes will spawn at the same time, during phase changes, no stun, you have 35 seconds before he's active again
• Stacking DoT that you have to pass around, disease (+250% damage taken) you have to pass around
• Ooze and Gas Variables debuffs appear, they want you doing damage to what matches you (Ooze to Ooze, Gas to Gas)

Blood Princes

• Every time you move, you get a stacking debuff that does shadow damage.   So like opposite of Hodir's debuff.

Blood Queen

• Aura increases in damage as more Vamps are out

Valithria Dreamwalker

• New constant shadow aura ticking throughout the fight, hurting her too
• Adds spawn faster

Sindragosa

• Ice Beacons in P1
• The backlash from Instability is a 20 yard aoe, not just to yourself

Lich King

• Shadow Traps, black things on ground that knockback explodes if you stand in them (right off the platform to your death)
