A complete breakdown of the Worm attack patterns and phases.
Worm Attacks
When I mention “Attack”, I am referring to one random attack out of these:
Acid Trail
Melee Attack
Triple Acid Spit
Single Acid Spit
Heavy Attack
Mines
⚠️ Notes:
Single Acid Spit does not count as a full attack.
Heavy Attacks enter the rotation in Phase 2.
Mines start appearing in Phase 3.
After Heavy Attacks are introduced, there will always be 1 guaranteed Heavy per rotation (between Acid Balls).
Every phase ends with a full rotation or is forced after the boss loses 30% HP.

The raid goes with this pattern almost always but the worm sometimes does random attacks during the raid. Single spits affect the rotations and Acid Trail almost guarantees the next big pattern.
