Fort Kearnhold 内部曲柄机构零件，击败 Banneret Toshtan 获取。
The Kearnhold Lock-Lever is a quest key item that drops from Banneret Toshtan during the Fort Kearnhold siege event chain. It is not a repeatable farm — you obtain it once by defeating Toshtan as part of the siege storyline progression and use it to unlock the inner keep mechanisms. There is no alternative farming method, no merchant source, and no enemy drop outside the siege event. If you missed the drop during your first siege run, replay the siege event and ensure you defeat Banneret Toshtan before progressing further.
