You create an illusory duplicate of yourself in an unoccupied space within 30ft of you. The duplicate seems completely real, including sounds, smells, and temperature appropriate to you. It can also manipulate objects (open doors, etc) though it can't attack. The duplicate has an action, and move action, and will immediately attempt to distract hostile creatures by whatever methods you or the DM deem appropriate. Creatures that can see it must make an Intelligence check against your spell DC or be fooled by the illusion. Once the duplicate is affected by an attack or spell or the spell expires, it vanishes in a puff of smoke.
Deadly Shade: At the time of casting, you can spend 2 Void Points to allow your duplicate to make melee attacks. It will have the same weapon and bonuses you do, and will also benefit from Sneak Attack (as well as count as an ally in range for Sneak Attack), if applicable. If your duplicate rolls a natural 20 or reduces a creature to 0 hitpoints, this does not consume a spell slot. Your Void Point Maximum is decreased by 2 for the duration of the spell, even if the duplicate is killed early.
Twin Shades: At the time of casting, you can spend 2 Void Points to summon two duplicates instead of one. Your Void Point Maximum is decreased by 2 for the duration, even if the duplicates are killed early.
