Encumbrance (装備変更不可, Soubihenkoufuka^?, lit. "Equipment Change Unacceptable") is a rare status effect in Final Fantasy XI which removes some or even all equipment from those affected and prevents them from re-equipping it for the duration of the effect. This status can be inflicted by special moves of monsters of several different families, and cannot be removed by any means short of death or its duration expiring.

Another very similar status, also called Encumbrance in English (エンカンバー, Enkanbā^?, lit. "Encumber"), is inflicted as part of the Pathos of Alzadaal on those who dare venture deep into the Ruins of Alzadaal to take part in Salvage. It is removed by leaving the ruins, or by obtaining and using cells that will unrestrict one or two equipment slots at a time. (In this case, even dying won't help.)
