Behavior

Thessal stays in the middle of the room, firing radial bursts of golden bullets while going invulnerable for a short time during this attack. She can sometimes gain stun immunity for a few seconds and fire rings of gold spirals that inflict armor break. She also continuously spawns Coral Bombs which blow up and split into more Coral Bombs, quickly causing large storms of bullets.

In addition, she constantly keeps a Deep Sea Beast on each of the 4 air vents in the room, making it much harder to regain air. If one dies, she will instantly respawn it.

Sometimes, she will quickly move into the center of the room, flash and become stun immune for a few seconds, and then fire several rings of highly damaging shockwaves that inflict Weak for 6 seconds.

As she loses health, her attacks gain frequency and her armor breaking bullets increase in number. When she is at low health, she gains an 8 second period of invincibility and fires her attacks much faster.

Occasionally and purely randomly, when Thessal is killed she will crumble over the loot bag and ask, “Is King Alexander alive?” If you respond with “He lives and reigns and conquers the world,” she will say “Thank you, kind sailor” and spawn 3 Coral Gifts. Otherwise, after a few seconds, she’ll shout “You speak LIES!” and suddenly attack. If you are standing on her (not smart), this will be instant death. Period.

Unlike before, Dying Thessal fires all her attacks simultaneously and constantly, making it much more difficult to put her down for good. She has an immense amount of HP in this form, but will self-destruct after a couple of seconds.

Tips and Strategies

If you have a small group or if you expect the fight to last a long time, it can be helpful to clear the room right before Thessal’s so that you have access to an air vent that is not guarded by Deep Sea Beasts. This also prevents unwanted confuse or paralyze enemies joining the fight. When in combat, do not hug Thessal, because she will sometimes move forwards very fast and instantly let loose a huge circle of shots. If you are hugging her, you won’t have time to back away, and her shots will do massive damage, which could lead to an insta-kill.

Trivia

Thessal is based of of a Greek legend called “The Legend of Thessalonike”. In the legend, Thessalonike was the sister of King Alexander the Great. When the King died, Thessalonike tried to kill herself by jumping into the sea, but became a mermaid instead of dying. She then asked sailors who encountered her: “Is Alexander the King alive?” She would only let them pass if they answered: “He lives and reigns and conquers the world.” Any other answer would cause her to fly into a rage and destroy the ship and its crew.

History

In Release X.12, the Thessal fight received a significant buff because it was considered to be extremely easy with even a small group of players, to the point of Thessal dying in seconds with a medium-large group. The following changes were made:

• Paralyze immune
• HP increased from 69,000 to 96,000
• Coral Bombs inflict Pet Stasis for 8 seconds
• Yellow Wall inflicts Weak for 6 seconds
• Increased Thunder Swirl Armor Break duration from 2.4s to 4.0s
• Can’t be stunned during Armor Break and Yellow Wall phases (warns with purple flash at the end of Tridents)
• Small invulnerability during Tridents (2.6s) and at the start of the last phase (8s)
• Shoots Tridents faster in the first phase, Armor Break slightly faster in the first and second phase
• All shots (including Coral Bombs’) now pass through players
• Deep Sea Beasts inflict Slowed for 2 seconds

In Release X.26, additional changes were made, which include reverting Thessal’s base HP back to 69,000 but giving her HP scaling this time, alongside the Coral Gifts which received a significant HP boost and HP scaling as well.
