Odd Blood Gems — Bloodborne
Odd Blood Gems — Blood gems, Bloodborne. Distinguish a flat point addition from a percentage and identify chest variants.

What “+77” means
A flat addition is not +77%. It adds attack points and does not scale with your stats. It is still subject to the target's defence.
Flat bonuses do not follow the move's multiplier in the same way as percentage bonuses. They can help at low attack values and with moves made up of small hits; compare the actual hit.

Accessing the treasures
These four routes are published with Fetid, Rotted and Cursed rites. The glyphs' current availability has not been verified. Flat elemental bonuses can also convert a compatible, purely physical weapon.
Gem effects and acquisition
Adds attack points that do not scale with stats. These points are still subject to enemy defence.
Compare the moves you actually use: a flat bonus does not follow the move's multiplier in the same way as a percentage.
Flat additions remain separate from percentages when calculating attack. Flat elemental bonuses can convert a compatible physical weapon.
| Effect | Value |
|---|---|
| Physical · coffin | +46.2 points |
| Fire or bolt · coffin | +77 points |
| Arcane · chest | +74.3 points |
Same unit, different effects
| Effect | Value |
|---|---|
| Percentage | +27.2% of the component |
| Flat addition | +77 points |
Flat points can help with low starting attack or weak individual hits. Compare the move's damage against the same target.
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.
