Four crystalline phases in impossible equilibrium. Tetra Barrier hardens whatever it joins.
Four-fold lattice reinforces whatever it is forged into.
How the waterline works. The game counts Tetrinite's share of the total crucible: under 10% the trait is INACTIVE; 10–30% it scales linearly (SCALING); 30–35% is OPTIMAL (full 18%); 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 Tetrinite (16%, SCALING at 13.8%). To max out you need +10 more — landing at 18/60 = exactly 30%. And a tiny 30-ore forge holding 2 Tetrinite needs +2 to wake the trait (4/32 = 12.5%).

Tetrinite carries a 23.5x crucible multiplier — S+ tier, divine rarity — sourced from Tower of Hell. A crucible loaded entirely with Tetrinite forges at exactly 23.5x.
Tetra Barrier caps at 30% of the crucible load: ceil(0.3 × N) ores — 15 Tetrinite in a 50-ore forge. At 10% it activates at 12%, reaching the full 18% at 30%.
Tower of Hell Wave 13 (T13) (Tower of Hell) at 1/436.
Tetrinite is top-tier forging material: 23.5x multiplier puts it among the strongest ores in the game, and the Tetra Barrier trait makes it a cornerstone of endgame recipes.
