The user uses a psychic force to pull a medium sized object or creature towards them. An unwilling creature would need to make a DC12 Strength save or be pulled in the direction of the user. The user is trying to pull an object from a creatures hands, the creature will need to make a DC12 strength save or have the object ‘yoinked’ from their grasp and if the user wants to catch the object they’d need to make a DC10 Dexterity save or be damaged by the flying object equal to the objects size (1D6 force damage for small, 1D8 for medium and 1D12 for a large object) if the object is a weapon the user takes damage equal to the weapons thrown damage, as if the weapon was thrown at the user. 

If yoink is cast as a bonus action on a creature that was affected by the ‘Yeet’ spell, the target makes the saving throw with disadvantage and if it fails the save, it is pulled towards the user and is dealt an additional 2D10 force damage.
