Thessal the Mermaid Goddess (Rev. 16)

Last updated: 9.0.0

Thessal the Mermaid Goddess is the boss of the Ocean Trench. The boss room has 4 air sources, that are each protected by a respawning Deep Sea Beast. If you are low hp, try to stay away from these as long as possible. Thessal will throw coral bombs that explode and split into 5 more bombs that explode to inflict more damage. This, combined with her armor breaking attacks, can make this fight a painful one.

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.

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.
