Important Primal Tsunami Trash Tips and Tricks

Once you have defeated the Khajin the Unyielding, the last gate of the dungeon will open, allowing you to enter the Infusion Chamber where you will find Primal Tsunami. Along the way, you will face some familiar faces like Glacial Proto-Dragon and Primalist Icecaller paired with several new mob types. Once you approach the bridge leading to the final boss, there will be a constant Crashing Tsunami either from the left or from the right. If you fail to dodge it, you will get knocked back. Here is more information on the trash mobs you will face on the way:

Dodging Crashing Tsunami

  • Aqua Rager is the first unique mob you will face, it has only one important cast to watch out for and that is
    its Boiling Rage Enrage effect. Once they reach 20% health, it will begin casting Tidal Divergence, dividing itself into 4 Aqualing. It is a 6 sec long cast, so it will be quite easy to interrupt it once you see it!
  • Once you approach the end of the bridge, the Crashing Tsunami will stop and Infuser Sariya will be available to be attacked. She will have unavoidable AoE damage coming from Inundate (non-interruptible) and an absorb shield cast that must be interrupted at all times – Aqueous Barrier. At last, get away from her Flash Flood AoE cast, it will knock you back and deal damage to you.

Primal Tsunami Tips and Strategy

Primal Tsunami boss encounter has two stages: Stage One: Violent Swells and Stage Two: Infused Waters. During Stage One, you will be fighting on the main platform (from where you pull the boss) until the boss reaches 100 energy, once he does that, it will cast Cast Away and begin its Stage Two. During this stage, you will be sent back to the beginning of the bridge (where you’ve entered originally), and your goal is to make your way back to the boss. Keep in mind, your team will be split in two (3 players in one corridor and 2 players in the other) and the Crashing Tsunami will be present once again! Here is a more detailed breakdown of the fight:
Primal Tsunami

All Roles

  • Avoid being hit by the Infused Globules ground spheres, during Stage One and Stage Two, failing to do so will deal high initial damage and trigger a secondary effect – Waterlogged.
  • During Stage Two, avoid the incoming Crashing Tsunami while you are making your way back to the boss. You will have to deal with 2 Primalist Infuser, defeating them will put an end the Stage Two. Upon this, the sequence of the spells and stages will repeat until the boss is dead.
  • Speaking about Primalist Infuser, it is important to interrupt the Infuse ability, since it empowers the boss. In addition, watch out for the Inundate cast!
  • On Mythic difficulty, the boss will cast an additional ability – Rogue Waves, dodge the incoming waves!


  • Be present in melee at all times to prevent the boss from dealing mass AoE damage to the entire party.
  • Use active mitigation once the boss is casting Squall Buffet. Not only will it knock you back, but it will also apply a follow-up effect – Focused Deluge. Your goal is to get as quick as you can in melee to prevent him from casting Undertow (dealing mass AoE damage to the entire party).


  • Periodically, Primal Tsunami will cast Tempest’s Fury, dealing AoE damage to all players. Be ready to top up the health of your teammates!
  • Dispel the slow effect from Waterlogged as quickly as you can.
