Heralds of Galactus
- Terrax: When the Rock Field starts, gain +1 Indestructible Charge Buff(s).

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 | 28,790 |
| 20 | 22,000 | 26,870 | 31,860 |
| 40 | 22,840 | 27,880 | 33,070 |
| 60 | 23,540 | 28,730 | 34,080 |
| 80 | 24,160 | 29,490 | 34,980 |
| 100 | 24,720 | 30,190 | 35,800 |
| 120 | 25,260 | 30,840 | 36,570 |
| 140 | 25,760 | 31,450 | 37,300 |
| 160 | 26,240 | 32,030 | 37,990 |
| 180 | 26,690 | 32,590 | 38,650 |

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.
