This faceted gemstone is the size of a coin and mounted on a golden disk covered in runes and scrollwork.

Soulstones are boons to all those who channel the power of incarnum (see Magic of Incarnum). When you use the proper command thought, this gem adheres to the center of your forehead (the same command thought causes the soulstone to disengage). While you wear a soulstone, you can bind a soulmeld to your brow chakra, gaining the normal ability granted by such a bind. This effect functions despite the fact that you are currently wearing a magic item in that chakra. This bind is in addition to any binds you are already allowed (though it doesn’t let you bind an extra soulmeld to your brow chakra). If you are already able to bind soulmelds to your brow chakra, the soulstone instead grants you 1 bonus essentia that can be invested only in a soulmeld bound to your brow chakra.
If you also wear a magic item that grants an enhancement bonus to your Wisdom, a soulstone also allows you to unshape a soulmeld bound to your brow chakra and immediately reshape another soulmeld, even binding it to your brow chakra if you want. This ability requires a full-round action and functions once per day.

Prerequisites: Craft Wondrous Item, bind a soulmeld to a chakra, essentia pool.
Cost to Create: 5,000 gp, 400 XP, 10 days.
