Bolt — Bloodborne
Bolt — Blood gems, Bloodborne. Compare percentage, flat addition and shape for a bolt 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
The Abhorrent Beast's Abyssal has a lower primary percentage but a stronger secondary effect. The source lists +33.8 flat bolt, among other variants: compare the move you use before favouring the largest percentage.
Where to find this variant
| Published effect | Shape and dungeon | Target and glyph |
|---|---|---|
| +27.2% bolt | Triangle · Isz, layer 1 | Merciless Watchers · 5pwujscd · rare |

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 bolt 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 |
| Abhorrent Beast | +33.8 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.
Two Abyssals, two secondary effects
| Effect | Value |
|---|---|
| Darkbeast: +24.8% and +15 flat | A × 1,248 + 15 |
| Abhorrent Beast: +22.5% and +33.8 flat | A × 1,225 + 33,8 |
| Both attack values are equal | A ≈ 817,4 |
A is bolt attack before gems. With one gem and no other bonuses, the Abhorrent Beast variant gives more attack below this threshold. Hit damage also depends on the move multiplier and enemy defence.
