First on the Scene
UNIQUE- All Champions except Chee'ilth: Regeneration Buffs and Passives gain 5% increased potency.

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 | 20,020 | 24,440 | 28,990 |
| 20 | 22,180 | 27,080 | 32,120 |
| 40 | 23,020 | 28,100 | 33,330 |
| 60 | 23,720 | 28,960 | 34,350 |
| 80 | 24,340 | 29,720 | 35,250 |
| 100 | 24,920 | 30,420 | 36,080 |
| 120 | 25,460 | 31,070 | 36,860 |
| 140 | 25,960 | 31,690 | 37,590 |
| 160 | 26,440 | 32,280 | 38,280 |
| 180 | 26,900 | 32,840 | 38,950 |
| 200 | 27,350 | 33,380 | 39,600 |
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.
