Tsoagoth, The Brine King is the final boss of Act 6, located in the Brine King's Reef. Defeating him is part of the main quest 
The Brine King.
Strategy
Tsoagoth is a challenging boss to strategise for, as his abilities intentionally remove the option of kiting (running out of damage zones) from the player. This boss acts as a stat check on your build. If you do not have enough lightning resistance and cold resistance, you are highly likely to die instantly by a combination of lightning strikes and orbs of water. In order to deal with this, it is recommended to max out lightning and cold resistances by temporarily equipping a Topaz Ring or Topaz Flask and Sapphire Ring or Sapphire Flask, in addition to having at least 1000 health and appropriate life flasks
Abilities
The stage and abilities change as the fight progresses.
At 100% health
Slam
Tsoagoth raises his claw and whacks the ground, creating a medium-ranged shockwave.
Cleave
Tsoagoth is capable of attacking in an arc. It applies the Maim status, reducing movement speed by 30% for 4 seconds.
Tidal Rush
Tsoagoth enters a defensive stance for 5 seconds, gaining 80% damage reduction, and damaging nearby enemies with cold damage. During this period, Tsoagoth is 40% slower, can only melee, and will constantly summon Brinespawn.
At 75% health
Flood Arena (1)
Upon reaching 75% health, Tsoagoth shrinks the arena with tidal waves. He is untargetable while the stage is shrinking. Tidal waves apply a debuff 
Tidal Wave on contact. For the duration, lightning will strike the ground, while orbs of water jump out of the waves. Even after the phase ends, orbs of water will occasionally continue to come out of the waves. The arena returns to a larger size, although smaller than it was originally.
Upheavel
He casts a spell on the ground, causing multiple bursts of cold damage in an area of effect.
At 50% health
Flood Arena (2)
Upon reaching 50% health, Tsoagoth shrinks the arena again, more than before.
At 25% health
Flood Arena (3)
Upon reaching 25% health, Tsoagoth shrinks the arena yet again, and more than the previous time. In this final phase of the fight, Tsoagoth will no longer use Tidal Rush. Instead, orbs of water and lightning will constantly strike the ground in random places until the end.
