What the patches changed
- Balance Patch 1 (2026-08-20) announced Attack Damage +20% — but the Week 1 notes admit that buff “didn’t actually make it in the last patch”, so the +20% never shipped.
- The Week 1 Update (2026-08-29) says it “deals more damage” and is “even stronger now” to make up for the missed patch. No replacement percentage is given.
- A heavy weapon, so it also received the Week 1 poise and damage pass applied to heavy weapons generally.
- Base damage numbers and scaling are still unpublished.
Reading the unlock rate
