Not an ore but crystallized bone — the marrow inside still feeds. Its Marrow Drain trait steals life with every hit.
Siphons health from every strike.
How the waterline works. The game counts Boneite's share of the total crucible: under 10% the trait is INACTIVE; 10–30% it scales linearly (SCALING); 30–35% is OPTIMAL (full 8%); past 35% it is OVERCAP — the trait stays maxed but the extra ores are wasted multiplier.
Exact top-up formula. Adding Δ ores also grows the total N, so the real formula is Δ₁₀ = ceil((N − 10n) / 9) for the 10% line and Δ₃₀ = ceil((3N − 10n) / 7) for the 30% sweet spot — never the naive "fill to 30%".
Worked example. Say your 50-ore crucible already holds 8 Boneite (16%, SCALING at 5.2%). To max out you need +10 more — landing at 18/60 = exactly 30%. And a tiny 30-ore forge holding 2 Boneite needs +2 to wake the trait (4/32 = 12.5%).

Boneite carries a 2.6x crucible multiplier — B tier, rare rarity — sourced from Forgotten Kingdom. A crucible loaded entirely with Boneite forges at exactly 2.6x.
Marrow Drain caps at 30% of the crucible load: ceil(0.3 × N) ores — 15 Boneite in a 50-ore forge. At 10% it activates at 4%, reaching the full 8% at 30%.
Bone Pile (Forgotten Kingdom) at 36.1%; Cursed Monolith (Forgotten Kingdom) at 20.0%.
Boneite is a solid mid-game ore — respectable 2.6x multiplier plus the Marrow Drain trait for weapons.
