Leviathan has 3 phases, during which he uses the following moves and mechanics.
Phase 1
Attack Name |
Description
|
Rip Current
|
Tankbuster. Shoots a long thin line AoE through the MT. Deals heavy damage to tanks and will one-shot anyone else.
|
Temporary Current
|
Leviathan moves his heads to the left or the right side of the arena and shoots a massive blue line AoE at a diagonal across the arena, leaving two small corners of space on opposite sides of the arena. Players need to move to those two safe spots ASAP because if they are hit by the AoE they will be flung off the arena and die.
|
Drenching Pulse
|
Drops large AoEs under random players' feet. Deals damage and applies a debuff if hit. Stacking up beforehand allows for more space to dodge the AoEs. Immediately followed by Freak Wave.
|
Freak Wave
|
Immediately after Drenching Pulse. Marks each player with a large AoE circle. Spread out and avoid stacking with others to prevent excessive damage.
|
Tidal Roar
|
Arena-wide AoE.
|
Tidal Wave
|
A giant pillar of water will appear at either the East or West. At the end of the cast, it will knockback players away from it, about ~50% of the arena. Immediately followed by Undersea Quake.
|
Undersea Quake
|
Immediately after Tidal Wave. The boss opens both mouths and they begin glowing with blue light. The heads will either split to reach both edges of the arena or be close together facing the center. At the end of the cast, the heads charge forward, crashing into and destroying parts of the arena in long line AoEs. Players caught in this will plummet to their deaths. The boss always destroys the floor in the same order, with the edges first, then the middle, and repeats until dead.
|
Crashing Pulse
|
Drops large AoEs under random players' feet. Deals damage and applies a debuff if hit. Stacking up beforehand allows for more space to dodge the AoEs. Immediately followed by Killer Wave.
|
Killer Wave
|
Immediately after Crashing Pulse. Obvious stack mechanic.
|
Tsunami
|
The boss swims around the top of the arena before hitting everyone for moderate damage. Also marks each player with a specific debuff with a varying amount of time on it.
- Surging Tsunami: Player is marked with a 360° knockback that pushes players about ~50% of the way across the arena, based on their orientation to the marked player. Marks 1 tank and 1 DPS. First debuff (tank) lasts ~8 seconds, and the second debuff (DPS) lasts ~30 seconds.
- Smothering Tsunami: Player will have a stack mechanic, requiring at least 3 people to stand with them to prevent lethal damage. Marks 1 healer. Debuff lasts ~16 seconds.
- Swirling Tsunami: Player will be marked with a large donut AoE. Marks 1 DPS. Debuff lasts ~22 seconds.
- Splashing Tsunami: Player will be marked with a medium AoE. Marks 1 tank, 1 healer, and 2 DPS. Debuff lasts ~22 seconds.

Maelstrom
|
Indicates the start of Phase 2.
|
Advice and Tips
- Tsunami order is > > + >
- During Tsunami, for + , the marked players should move out and let everyone else stay stacked in the middle. Whoever has should move to the front of the arena so players are knocked towards the back of the arena to help with later mechanics.
Phase 2
Attack Name |
Description
|
Spinning Dive
|
A blue water portal will appear on one side of the arena. After a moment, the boss will charge through, hitting 50% of the arena for heavy to lethal damage and applying a Vulnerability stack. Occurs at the same time as Dropsy Puddles.
|
Dropsy Puddle
|
3 tiny puddles appear that then expand into giant AoE puddles. Standing in these puddles applies a ~12 second DoT and deals damage. Occurs at the same time as Spinning Dive.
|
Advice and Tips
- Repeats both attacks twice before returning to the arena, signaling the start of Phase 3.
Phase 3
Repeats all mechanics from Phase 1.
Advice and Tips
- Tsunami is combined with Undersea Quake, where only the center of the arena remains. Adjust knockbacks accordingly.
- Temporary Current is combined with Undersea Quake, where only the sides of the arena remain. Be prepared to move North or South to the safe corners.
