UNIQUE- Guillotine (Deathless): Souls last 30% longer and are paused during either Champion's Special Attacks.
- Guillotine: The potency of healing from damage taken by the Opponent is increased by 66.6%.

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.

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.
