Reduvia

The Reduvia is a Dagger in Elden Ring. B Arcane at max standard with 50 blood loss, plus Reduvia Blood Blade, a ranged skill.

When to Use It

Early game. It is found around Murkwater Cave, in the opening stretch of a run, so it is one of the first real upgrades you can carry.

13 Arcane requirement; obtainable very early from Bloody Finger Nerijus at Murkwater Cave.

Reduvia Blood Blade costs 6 FP.

Slash with the wicked dagger, transforming its never-drying bloodstains into airborne blood blades that cause hemorrhaging. Can be fired in rapid succession.
Unique to this weapon. It cannot be moved onto another weapon, and no Ash of War can replace it.

It scales Str E, Dex D, Arc D, so Dex and Arc are where the levels go.

Requires Str 5, Dex 13, Arc 13.
Takes no Ash of War and no affinity, so the build has to come to the weapon rather than the other way round.
Causes blood loss buildup, without any infusion needed.

Critical 110. A backstab, or a riposte after a guard break, is multiplied by this, where 100 is the baseline most weapons carry.

2 weapons of its class reach higher, topping out at 140.
It pays for getting behind an enemy or breaking their stance rather than trading hits in the open.

Jagged dagger with a distinctive curved blade. Used by the noble servants of the Lord of Blood.
This dagger rips the flesh as it enters, inflicting blood loss with sickening efficacy. A proud testament to the success of its vicious design, this weapon is perpetually coated in blood.

Dropped by Bloody Finger Nerijus near Murkwater Cave once defeated.
Beware that progressing through the game can prevent this invasion from happening, more specifically by defeating all the major Limgrave bosses (Flying Dragon Agheel, Mad Pumpkin Head, Margit, the Fell Omen, Tibia Mariner, and Tree Sentinel).
