A manual lock doubles Kuva per roll: 3,500 → 7,000 at the capped cost. A spliced trait stays fixed for free, with one extra manual lock available. Locking or retaining a splice preserves the selected format. Locked estimates require a starting Riven in that format; acquiring it and splicing setup costs are excluded.
