Element resistance
Status resistance
0% neutral · Negative: more damage · 100%: immune · 200%: absorbs. Status percentages are resistance, not infliction chances.
Drops
Steals
Drop percentages are base chances before bonuses. Steal slot probabilities are still being verified.
Attack Pattern
Opens by swallowing a party member, then continues attacking. Weakness hits and staggering can force an early release.
Numbers count this boss’s own actions; combos are listed together. Battle-turn rules are labeled.
| When | Action |
|---|---|
| Opening, and once ready to swallow someone again | Use Swallow. After releasing someone, prepare the swallowing move again by completing two qualifying attacks: the first or third attack of the normal pattern at HP 60% or above, or the second or third below 60%. |
| HP at least 60%: repeat steps 1 → 2 → 3 | Choose from Crush (50%) or Bonebreaker (30%) or Flatten (20%) → 30% Thwack / 70% Mucus → 30% Gravity / 70% Stonera. |
| Below 60%: repeat steps 1 → 2 → 3 | Choose from Regurgitate (20%) or Regurgitate (10%) or Regurgitate (10%) or Regurgitate (20%) or Regurgitate (10%) or Regurgitate (10%) or Regurgitate (10%) or Regurgitate (10%) → 30% Secrete Acid / 70% Thwack → Stonega. |
| After five attacks while holding someone | Use Regurgitate to release them before the normal attack. |
| If nobody can be swallowed | Use 30% Thwack / 70% Mucus and continue the normal pattern. |
Pattern Changes
- Four weakness hits while holding someone force Regurgitate to release them. Staggering or defeating the boss also forces this release.
- After recovering from a stagger, use four to six random attacks from Regurgitate (20%) or Regurgitate (10%) or Regurgitate (10%) or Regurgitate (20%) or Regurgitate (10%) or Regurgitate (10%) or Regurgitate (10%) or Regurgitate (10%).
- If no active party members remain while someone is held, release them with Regurgitate.
