凯恩霍德围攻任务道具，击败 Banneret Anara 获得，用于开启堡垒后门；一次性获取。
Kearnhold Key is a quest-specific tool obtained by defeating Banneret Anara during the Fort Kearnhold siege quest chain. The key is a one-time acquisition that grants access to the back entrance of Fort Kearnhold. Banneret Anara is a named foe encountered during the siege storyline — progress the Kearnhold siege questline until the encounter triggers. The key is not a repeatable drop and no merchant sells it. If the key is missing after the encounter, check quest journal steps rather than re-farming Anara.
