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.
58 LIVE weapons does not mean every combat stat is complete. Documented verified coverage: scalar damage 29/58, model-aware damage 33/58, legacy scalar RPM/TTK 4/58. Unverified values are labeled and never shown as zero.
