Where you fight it 1
Each place uses its own copy of the boss with that area's scaling. HP and stance as you meet them (first phase, offline, no new game plus).
| Place | HP | Stance | Scaling |
|---|---|---|---|
| Swamp of Aeonia · Heart of Aeonia | 9,210 | 90 | ×3.25 |
Damage negation
How much of each damage type it shrugs off. Lower is better for you; the type it takes most is highlighted.
Flat defense
Subtracted from each hit before negation; it matters most for weak hits. Area scaling raises it along with HP.
Status buildup to proc
Buildup needed for the first proc, and how much more each following proc needs (it grows after every proc, up to the fifth).
| Status | 1st proc | 2nd | 3rd | 4th |
|---|---|---|---|---|
| Poison | 332 | 430 | 720 | 1,177 |
| Scarlet Rot | Immune | |||
| Bleed | 332 | 430 | 720 | 1,177 |
