Rainbow Six Siege Y11S3.1 Adjusts Six Operators in Refinement Pass

Ubisoft's Y11S3.1 patch for Rainbow Six Siege arrives as a declared refinement pass — changes framed explicitly around polish, consistency, and quality-of-life rather than power-level shifts.

What changed

Attackers

• Buck – Skeleton Key: Total ammo increased to 36 (was 31), extending his vertical-play utility across longer rounds.
• Sledge – Breaching Hammer: Swing time reduced to 0.8 seconds (was 1 second), improving gadget responsiveness.
• Thermite – Exothermic Charge: Damage increased to 220 hp (was 200 hp), raising the risk for Defenders standing close to reinforced surfaces when a charge detonates.
• Sledge / Thermite shared weapon – M1014: Base damage increased to 30 hp (was 28 hp), targeting close-quarters consistency without extending effective range.

Defenders

• Castle – Armor Panel: Melee hits required to destroy a barricade increased to 10 (was 9), adding friction to Attacker breaches.
• Fenrir – F-NATT Dread Mine: Time for gas to reach maximum range reduced to 1.9 seconds (was 2 seconds), sharpening reaction timing.
• Maestro – Evil Eye: Battery life increased to 9 seconds (was 8 seconds), improving gadget consistency over the course of a round.

Taken together, the patch nudges several underperforming gadgets toward more reliable moment-to-moment performance — a maintenance update rather than a shakeup, but one that meaningfully touches both sides of the roster.
