Sszorak is the third or fifth boss of The Venomous Abyss raid, depending on your route . 

Sszorak is a one-phase fight that repeats mechanics until defeated. This fight contains several pushback and knockback mechanics, so players will need to be ready to move in a hurry! This boss has a 30% damage amp while casting Dig In, which lasts for 25 seconds and occurs roughly around the 2-minute mark of the fight. Be sure to save cooldowns for this moment and burst as much damage as possible! 

• Some players will get blue wind circles around them with a "line thicker at one end" indicating the direction they're about to be blown.  Players can stand up/down wind of someone else with a line pointing the opposite way, so they bounce off one another.

• Tank combos (tank swap on each one): 

  • Ravage (white) cone frontal for a tank only.

  • Mutilate (green) cone frontal which is a group soak.

  • A bunch of green tornadoes that shoot outwards in all directions.

• Tank Stacking Debuff - Corroding Venom.  Taunt when it falls off/stacks get too high.

Intermission:

• Position boss at the centre of the room BEFORE he casts "Dig In".  First tornado will activate, attempting to push everyone off.  Once the first person hits the floating blob, everyone will get knocked back from it - make sure you're stacked!  Repeat for 2 and 3.  

• Any blobs hit will disappear.  Any blobs left will explode with a knockback - beware!
