At-will, std, touch range, 4 Vitae; you animate an inanimate object of your approximate size, which morphs into an exact copy of yourself. This construct, called an eidolon, serves you loyally and follows your commands to the best of its ability.

You may give the eidolon spoken commands as a swift action. It understands all languages that you do. It can perform any physical action that you are capable of, and can even cast spells or use powers, but you have to pay the energy cost for any spell or power it uses.

It receives facsimiles of all mundane equipment you are carrying, but your magic items are duplicated only as magicless mundane items. You can give a magic item to the eidolon, and it can use it normally.

At any time, as a swift action, you can concentrate to 'possess' the eidolon, seeing and hearing through its senses, and controlling its actions directly. While possessing the eidolon, you cannot take any actions with your own body, and you are vulnerable to attacks targeting it.

The eidolon has its own health pool equal to half your maximum health (rounded up). If the eidolon is reduced to 0 health, it is destroyed, and you immediately return to your own body if you were possessing it.

The eidolon has no range restriction once created. You do not have to concentrate to keep it active, but at the dawn of every day after you create it, you must spend another 4 Vitae to maintain its animation. If you do not, it crumbles to inanimate matter.

You can have only one eidolon active at a time. Creating a new one causes the previous one to crumble to inanimate matter.
