Tempering — Bloodborne
Tempering — Blood gems, Bloodborne. The versatile choice for physical, blunt, thrust and blood damage components.
What the bonus strengthens
The physical bonus also covers thrust, blunt and blood. It does not strengthen fire, bolt or arcane damage. A converted weapon therefore loses the benefit of its physical gems.
Compare variants
| Published variant | Benefit |
|---|---|
| +27.2% physical · rating 19 | High percentage with no positive secondary effect |
| +24.8% physical + secondary effect · Abyssal, rating 20 | Compare the secondary effect with the percentage gain |
| +21% physical + stronger secondary effect · rating 18 | Specialised option depending on the secondary effect |
Bonuses multiply
Three +27.2% gems give 1.272 × 1.272 × 1.272 ≈ 2.058, or about +105.8% to the affected attack before damage calculation. Enemy defence means this figure cannot be treated as the final damage gain.

Gem effects and acquisition
Strengthens physical, thrust, blunt and blood components. Elemental damage remains outside the bonus.
A physical or blood component must be present. After elemental conversion, a physical gem no longer strengthens the converted damage.
Compatible percentages multiply across gems. Flat additions remain separate from the product of percentage bonuses.
| Effect | Value |
|---|---|
| Watchers | +27,2 % |
| Abyssal | +24.8% + secondary effect |
| Without chalices · expansion | Up to +22.3% |
One or three identical gems
| Effect | Value |
|---|---|
| One gem | +27,2 % |
| Three gems | +105,8 % |
Calculated on the affected attack component, before enemy defence. This percentage alone does not predict the damage of a hit.
Percentage or flat addition: a worked example
| Effect | Value |
|---|---|
| One +27.2% gem | A × 1,272 |
| One +24.8% and +15 flat gem | A × 1,248 + 15 |
| Both attack values are equal | A = 625 |
A is the component's attack before gems. With one slot filled and no other bonuses, the second gem gives more attack below 625; above that, the first does. Move multipliers and defence still need to be applied to compare actual damage.
