Thoth's Duplicate

You harness the wisdom and power of the god Thoth to summon a duplicate of yourself. The duplicate is identical to you visually unless inspected against your spell save dc. The duplicate has a score of 10 for each of its stats and is summoned with hp equal to half your maximum hp. The duplicate is friendly to you and your companions. It follows your commands and wishes and acts on your turn. When you summon the duplicate, you also cast one other 1st level or lower spell. The duplicate gains one spell slot of the level spell that you cast and now has that spell prepared. The duplicate has access to no magic otherwise. The duplicate has no equipment but does appear as though it has all of the equipment you had when it was summoned. The duplicate is dispelled and dies when it is reduced to 0 hp, when it uses the spell it was given, or you break concentration. When the duplicate casts the spell all modifiers and effects are treated as though you casted it. You can only have one of these duplicates at a time. The duplicate can remain for up to a day but every 30 minutes of concentration, you must make a DC15 constitution check to maintain concentration.

When cast with a level 3 or higher spell slot, the maximum level of spell you can give to the duplicate is equal to the level this spell is cast at -1.
