短刃 Utility 槽稀有符文。完全蓄力重击后进入暗影隐身 6 秒，每次潜行击杀延长 3 秒。
The Flitsmoke is a Rare short-blade Utility rune dropped by two Cogah Agari bosses. Best route: Etheldred The Weaver — a world Agari in the Glades arena (Cogah) with a ~3-hour respawn. Use The Cogah elixir (crafted from Agaric Mushrooms dropped by Agari) to activate Cogah hard mode, which increases drop rates and enables unique rune drops. Ring the arena bell to begin the encounter. Etheldred also drops The Cogah Creutair and Emberaught, so multiple runes can be farmed per kill. Alternate source: Seachnall The Widower, a dungeon Agari in Cogah. Neither kill guarantees a Flitsmoke drop — expect multiple runs.
Foe: Etheldred The Weaver — Cogah — Glades arena, world Agari, ~3h respawn
Foe: Seachnall The Widower — Cogah — dungeon Agari
Cogah hard mode: crafted The Cogah elixir from Agaric Mushrooms
