Handle with tongs. This glowing nightmare leaves an Irradiated Edge that keeps melting enemies after the fight ends.
Radioactive flakes keep searing long after impact.
How the waterline works. The game counts Uranium's share of the total crucible: under 10% the trait is INACTIVE; 10–30% it scales linearly (SCALING); 30–35% is OPTIMAL (full 10%); 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 Uranium (16%, SCALING at 7.2%). To max out you need +10 more — landing at 18/60 = exactly 30%. And a tiny 30-ore forge holding 2 Uranium needs +2 to wake the trait (4/32 = 12.5%).

Uranium carries a 3x crucible multiplier — B tier, epic rarity — sourced from Forgotten Kingdom. A crucible loaded entirely with Uranium forges at exactly 3x.
Irradiated Edge caps at 30% of the crucible load: ceil(0.3 × N) ores — 15 Uranium in a 50-ore forge. At 10% it activates at 6%, reaching the full 10% at 30%.
Cursed Monolith (Forgotten Kingdom) at 14.3%.
Uranium is a solid mid-game ore — respectable 3x multiplier plus the Irradiated Edge trait for weapons.
