Bisulcam 剧情用 Ode'n 能量球，为巨炮供能。仅在击败 Banneret Kylst 的任务线中获得，不可重复刷。
Bisulcam Fodder is a Common event item, an Ode'n Sphere used to power the mighty Bisulcam cannon during the Bisulcam storyline in Preludes 15. It is obtained exclusively from Foe: Banneret Kylst during the Bisulcam quest chain — defeat Kylst at the assigned encampment to receive the fodder as a one-time quest reward. This is a story-progression item, not a repeatable farmable drop; once the Bisulcam storyline is complete, Banneret Kylst does not provide additional Bisulcam Fodder. No merchant sells this item, and it does not appear in any container or additional foe loot tables. If you are looking for Bisulcam-related drops for combat or crafting purposes, note that the Bisulcam boss itself drops materials like Quicksilver and Dracs, but not Bisulcam Fodder — those are distinct from this quest-specific item. Verify your current quest stage in the Fables log if Banneret Kylst is not spawning at the expected encampment location, as quest progression determines when the encounter becomes available.
