New Mutants
UNIQUE- Mutant Champions: Ability Accuracy is increased by 30% during Special Attacks. Increased to up to 60% based on Sunspot's Signature level.

Every sig anchor × rank at A0. Sig levels in between interpolate smoothly (PCHIP) and round to the nearest 10 BHR — matching the in-game display.
| Sig | R3 | R4 | R5 |
|---|---|---|---|
| 0 | 19,880 | 24,270 | 28,780 |
| 20 | 22,040 | 26,920 | 31,920 |
| 40 | 22,880 | 27,940 | 33,130 |
| 60 | 23,580 | 28,790 | 34,140 |

BHR at each signature level by rank (non-ascendable — A0 only). The curve is concave — sig 0 → 100 captures roughly two-thirds of the gain from sig 0 → 200.
