Fire — Bloodborne
Fire — Blood gems, Bloodborne. Compare percentage, flat addition and shape for a fire setup.

On a compatible weapon
The percentage only strengthens its own damage type. On a convertible, purely physical weapon, the elemental addition changes base damage and makes its scaling depend on Arcane.
On a weapon with native mixed damage, the bonus does not convert the physical component. Check which damage line actually increases on the weapon screen.
Compare variants
Loran can provide a flat fire secondary effect on an Abyssal. The same secondary effect is not native to Pthumeru: a radial and a waning gem with the same percentage do not require the same search.
Where to find this variant
| Published effect | Shape and dungeon | Target and glyph |
|---|---|---|
| +27.2% fire | Triangle · Isz, layer 1 | Merciless Watchers · 5pwujscd · rare |
| +24.8% fire + secondary effect | Waning · Lower Loran, layer 3 | Watchdog of the Old Lords · 758v8txa |
| +24.8% fire + secondary effect | Radial · Pthumeru Ihyll, layer 3 | Watchdog of the Old Lords · 7vvid666 |
These routes use Fetid, Rotted and Cursed rites unless stated otherwise. Values describe possible variants, rather than guaranteed drops. The glyphs are published in the wiki; their online availability has not been verified.
Gem effects and acquisition
The fire damage percentage only strengthens that component. An elemental gem can convert a compatible, purely physical weapon.
After conversion, damage scales with Arcane. A weapon with native mixed damage keeps its separate components.
Compatible percentages multiply across gems. Flat additions remain separate from the product of percentage bonuses.
| Effect | Value |
|---|---|
| High percentage | +27,2 % |
| Abyssal alternative | +24.8% + secondary effect |
| Watchdog | +15 flat points |
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.
