This mod adds a book that will teach you a spell that will allow you to summon a duplicate of yourself which has all your abilities, follows you and fights for you, as well as engages in harmless conversations with npcs.
Imperial City, Market District, First Edition, Phintias has a book for sale called "Reflective Tome."
On the heels of his successful aquistition of the legendary scroll "Creatures of the Etherial Planes" (i.e. my "Summon Unicorn (Summon Horse)" mod at Tessource.net) Phintias at the First Edition in the Imperial City Market District has gotten ahold of a unique book and is willing to sell it.
Upon purchasing the book "Reflective Tome" the player will gain the spell "Summon Doppleganger" which temporarily summons an exact copy of the player which follows the player, assists him in combat, has all the abilities of the player, and can serve as an interesting sparring patrtner. (feel free to sell the book back after reading it to recoup some of your cost).
-If you delete the junk spells out of your spell list then your Doppleganger won't waste time casting them, otherwise he has full access to any spells the player has.
-Guards may defend him if you attack him depending on your factions.
