Hunger for the Stars
- Solvarch: Build an additional 5 Core Charge for each full Bar of Power remaining when activating a Special Attack.

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 | 20,030 | 24,450 | 29,010 |
| 20 | 22,170 | 27,060 | 32,100 |
| 40 | 23,010 | 28,080 | 33,320 |
| 60 | 23,720 | 28,940 | 34,340 |
| 80 | 24,340 | 29,700 | 35,240 |
| 100 | 24,910 | 30,400 | 36,070 |
| 120 | 25,450 | 31,060 | 36,850 |
| 140 | 25,950 | 31,670 | 37,580 |
| 160 | 26,440 | 32,260 | 38,280 |
| 180 | 26,890 | 32,820 | 38,940 |
| 200 | 27,340 | 33,360 | 39,590 |
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.
