🔥 Dreadplate — the 10% / 30% waterline

How the waterline works. The game counts Dreadstone's share of the total crucible: under 10% the trait is INACTIVE; 10–30% it scales linearly (SCALING); 30–35% is OPTIMAL (full 22%); 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 Dreadstone (16%, SCALING at 16.4%). To max out you need +10 more — landing at 18/60 = exactly 30%. And a tiny 30-ore forge holding 2 Dreadstone needs +2 to wake the trait (4/32 = 12.5%).
