Unseen Thing

EN

This spell is capable of creating a single invisible non-magical object in your hands. While concentrating on the spell the caster cannot speak any words directly related to the created object or else the object is dismissed. As a bonus action the object's shape can be changed by touching it and expressing through fast hand movements it's new form. The object's volume cannot be bigger than 5-foot-cube and can't weight more than your carrying capacity. If you want to use the object to interact targeting another creature , the target must make a charisma saving throw, if it fails the target now is susceptible to interactions with the invisible object until the spell ends. If the target succeds it is immune to the created object for the next 24h. In order for allies to use or manipulate the invisible object, they must overcome a performance check (DC:10). If you change the shape of the object after targeting an enemy with it, you now have advantage with the next action involving the object, depending on the action you take the enemy can have disadvantage on the ability check referent to the action(for exemple if you try to imprision the enemy with a invisible sword that now is a rope, or attack with a rope that now is a sword. The enemy is unprepared  so it cannot expect what is going to happen.). 

 If used as a ritual, this spell does not require concentration, allies who witnessed the ritual don't need to succed the performance check to use the object, but the shape of the created object cannot be changed.  This spell cannot be prevented by the Dispel Magic spell unless the object's name is said out loud. An Unseen Thing's AC can range from 11 to 10 + your spell casting modifier, based on the aspects of the object you want to create.

Using some invisible objects still requires proficiency for proper use.
