Attachments tuned:MFS Deflection Core
Source: official patch notes ↗The Siren maxes out at weapon level 30. After that you can enter weapon prestige and unlock its prestige attachment.
We list 3 compatible attachments for the Siren across 2 slots, each with its unlock level and what it does.
The prestige attachment is the MFS Deflection Core. It unlocks after you reach max level and enter weapon prestige.
The last official change to the Siren was in Season 06 (2026-11-05). The patch notes have changed it 1 times since launch — all listed in the History tab.
In the same class: GDL Havoc, Grimhawk, NX Ravager. Each has its own page with level-by-level builds.
Sign in to save this build and track weapon level. The page stays usable without an account.
Enter your Siren level and pick a playstyle to get a useful build.
