Duelo Mestra 的亚麻流苏头盔，击败 Mestra Carmo 获取或 community catalog 购买（245 Dracs）。
Mestra's Helm drops from Mestra Carmo, the Duelo Mestra Agari encountered on the southern coast of the Salz Sea. The fight has a community-reported cooldown of roughly 2 hours between spawns — after defeating her at the shipwreck site, you can re-engage by revisiting the area once the cooldown resets. For a single missing piece, the Avakot merchant sells it for 245 Dracs when stocked, which is often faster than waiting for spawn cycles.
