Unseen Assassin

With your mastery of the manipulation of the Weave, you can project an invisible humanoid into existence. You can see and hear through this manifestation and control it’s actions. 

As an action, you can conjure an invisible magical construct whose actions you control. While active the only actions you can do is Intelligence, Wisdom, and Dex(Stealth) based skill checks. You can also perform 1 attack before the spell ends using your stats and it can benefit from your sneak attack class feature. Once the attack happens, hit or miss the spell immediately ends. The construct does not trigger any traps that require pressure or a presence to activate such as a tripwire or the Arcane glyph spell. If the construct suffers any damage, the spell immediately ends
