Past and Present Self
UNIQUE- Synergy Champions: Striking an Opponent with a Critical Hit inflicts a non-stacking Degeneration Debuff dealing 50% as Direct Damage over 6 seconds.

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 | 20,060 | 24,490 | 29,050 |
| 20 | 22,150 | 27,040 | 32,080 |
| 40 | 22,990 | 28,060 | 33,290 |
| 60 | 23,690 | 28,920 | 34,310 |
| 80 | 24,320 | 29,680 | 35,220 |
| 100 | 24,900 | 30,380 | 36,050 |
| 120 | 25,430 | 31,040 | 36,820 |
| 140 | 25,940 | 31,660 | 37,560 |
| 160 | 26,420 | 32,240 | 38,250 |

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.
