Navalha 的武器碎片，完成 The Wreck of Mestra Carmo 传说后授予首片；与 Duelo 盟约同线解锁。
Navalha Fragment is a Rare weapon-fragment used to craft the Navalha rapier at Tuvalkane. The first fragment is guaranteed from completing The Wreck of Mestra Carmo fable — a one-time story acquisition. For extra copies needed to repair or reforge: farm Foe Blue Ribbon Crew encounters, or loot the Pigwen Skerry Chest. The community catalog travelling merchant also stocks Navalha Fragment at 220 Dracs (qty 1) when available — use merchant buys as a finisher when one fragment short of craft. No drop rate is published; expect multiple runs for duplicate fragments. Pair the Blue Ribbon Crew farm with other loot from the same encounter circuit.
Foe: Blue Ribbon Crew
Container: Pigwen Skerry Chest
Avakot merchant — 220 Dracs, qty 1
