Bone Rune
Raises your maximum HP by a percentage (scales into the endgame)
Effect by tier (roll range)
| Tier | Effect |
|---|---|
| I | +3–6% max HP |
| II | +7–12% max HP |
| III | +14–22% max HP |
Crafting always yields Tier I with a roll inside the range; merging three identical artifacts climbs a tier, reforging rerolls within the full range (a max roll shows as Perfect).
