Magic Device Attunement

(Complete Mage, page 44, DnD 3.5)

[General]

You have a knack for activating familiar magic items.

Prerequisite

Use Magic Device 1 ranks

Benefit

If you successfully activate an item with the Use Magic Device skill, you can take a free action to attune yourself to the item. For the next 24 hours, you can activate that item without making further Use Magic Device checks. You can attune yourself to only one item at a time. If you attune yourself to a second item, the previous attunement ends.
