Build it. Thirty percent crit at 3x on silent throwing daggers is the best crit line of any thrown secondary, and kills pin bodies to walls. Travel time is the only cost. Vaulted, so it is a trade or a Resurgence wait.
Ragdolls and pins the target to the wall on a kill. Ragdolled bodies fly in a straight line and can damage other enemies in its path.
The Spira Prime is the Prime variant of the Spira throwing daggers, released alongside Saryn Prime and Nikana Prime. It features increased fire rate, reload speed, status chance, and critical multiplier compared to its base version, in exchange for reduced base damage.
This weapon deals primarily Puncture damage, making it effective against armored targets. It is also a silent weapon, which can be beneficial for stealth gameplay.
The Spira Prime is notable for having one of the highest critical chances among throwing-type secondaries and a high critical multiplier among all secondaries, positioning it as a strong contender for critical-focused builds.
How to get the Spira Prime
- The Spira Prime is vaulted: its relics no longer drop in missions. Open relics you already own, buy them for Aya when Prime Resurgence lists it, or buy the parts for platinum.
- Pouch: Lith S1, Lith S3, Lith S6, Meso S15, Meso S3 and 3 more (vaulted relics; the rare slot in Lith S1, Lith S3).
- Blade: Lith S5, Meso M5, Meso S6, Neo S10, Neo S3 and 1 more (vaulted relics; the rare slot in Lith S5, Meso S6).
- Blueprint: Lith C5, Lith N2, Lith S17, Lith V4, Meso S9 and 4 more (vaulted relics).
- Run the fissure tier that matches each relic, refine the rare part’s relic to Radiant, and pick the best of the four results with a squad.
- Build the parts, then the weapon: 12 hours each, or rush with platinum.
