The Blight of Giegex
Weapon (dagger), uncommon (requires attunement by a rogue)
When you throw this dagger at a target, instead of actually throwing the dagger, an illusory version with full physical similarity is thrown. If the illusory dagger strikes a creature, it immediately disappears in a 5 foot puff of smoke, preventing the target from taking reactions until its next turn. If the illusory dagger strikes an object, it becomes embedded in the item, and the wielder can use an action to retrieve both the illusory dagger and the item it is embedded in. Only one of these illusory daggers can exist at a time.
