It has been gathering power in the depths.
It is faster, stronger, deadlier.
It has returned to devour and destroy.
It is called Tequatl the Sunless… and it has evolved.

 Tequatl Rising
- Primary article: Defeat Tequatl the Sunless
- The event has a 15:00 minute time limit.
- Tequatl has new combat mechanics
- A Scales effect that summons a Bone Wall and makes Tequatl invulnerable until the wall is destroyed. Turrets have skills to remove stacks of the Scales effect.
- Stomps the ground, sending out a tidal wave that knocks players back and can hit multiple times. Players can jump over and dodge through the wave, similar to the fight with King Toad.
- Tequatl's Fingers will continuously be summoned on the field, requiring players to take them out to avoid being constantly knocked around.
- Spews poison fields across the area. These pulse every second, inflicting damage and poison. Turrets can be used to remove the poison fields.
- Summons vines that pull players under the bog if they get too close. They will take continuous damage and must swim to the surface to get back to the fight.
- Tequatl changes combat phase at every 25% health to a secondary phase. On a secondary phase, an event starts where players must defend three batteries arranged around a cannon.
- If the event fails, Tequatl will send a giant tidal wave that will wipe out players unless they use the launch pads to avoid it. Risen Rotmouths will appear in the area until Tequatl returns.
- Launch pads reminiscent of Lightning Pull move players to and between the cannon and batteries.
- New reward system
