Ring of Vanishing

This object is a featureless, clear glass ring.

A ring of vanishing allows you to briefly become almost entirely imperceptible. When you activate this ring, you become invisible (as greater invisibility), as well as undetectable by hearing, scent, blindsense, blindsight, or tremorsense, for 2 rounds. Spells or effects that detect invisible creatures (such as see invisibility or true seeing) still function normally.

This ability functions three times per day.

Prerequisites: Forge Ring, greater invisibility.

Cost to Create: 15,000 gp, 1,200 XP, 30 days.
