The Lost City of Barakus
Cloth of Identification
Wrapping a magic item in it for 30 minutes duplicates the effect of an Identify spell.
It is the size of a beach towel.
It must cover at least 75% of the item to work.
As the party does not have a spell caster with the Identify spell, this is the only way that magic items can be identified.
It is large enough to identify most, but not all, magic items.
