Deep Sea Corruption

• Deep Sea Corruption is a weekly mission given by Loyalist Iona in Mera's Royal Hideout in the bottom level of the southern edge of Atlantis open world zone.

• (Weekly) The dark magic that Corum Rath has released upon Atlantis has driven the Beastmaster's brinehulks insane, turning one of them into a giant coprrupted monster. Take him out before he destroys the city.

• Brine Hulk

• The mission requires you to defeat the giant Brine Hulk in the farm in southeastern Atlantis. It has several attacks:
• Goo Projectile: Sprays green spheres in that roll in all directions, trapping any players they hit which cannot be broken out of normally and you must spam the left mouse button to free yourself faster while it deals heavy continuous damage.
• Toxic Spit: An unavoidable ranged attack that knocks you down and deals relatively low damage over time.
• Melee Attack: A standard melee attack that nevertheless can do massive damage in each hit (up to at least 50000 at minimum defence). There is also a Lethal attack version that is a charging slam with the same name.
• Sonic Stun: Stuns and deals moderately heavy damage to all targets in a huge area.
• While obviously much easier with a team, it is conceivable to solo it in Flight (if you are standing on ledges and the Brine Hulk can't reach you, it will Evade and reset its health). Both of its more dangerous attacks, Melee Attack and Goo Projectile, can't hit you in the air, and it lacks a true grounding attack (both ranged attacks disables you, but can be broken out of normally). Sonic Stun is a bit more dangerous due to its higher damage and with no warning, but with pets it would spend most of its time using Melee Attacks and Goo Projectiles on them. With multiple Shield Powers they would be able to fully keep up with Toxic Spit's damage, and you will only occasionally take a spike hit from Sonic Stun.
• Warning: Do not lure the Brine Hulk far away from its spawning point. There is a danger that it resets health and you need to start over. It can also charge at players or pets and get itself stuck in one of the nearby pens - if it can't reach players eventually it would also reset.
