Magical Item: Attunement

Any item attuned to an NPC under your control (such as, but not limited to, familiars, beast companions, simulacrums, conjured creatures, hirelings, lickspittles, etc.) counts against both the controlling character’s limit of three attuned items and the character’s permanent magic item count. Note that this does NOT mean that all are attuned to the same item. Each controlled creature must spend the time to attune to the item, but the total number of attunement slots are limited.
