Ball of Monster Capture

the Ball of Monster Capture is a palm size sphere with a crystal embedded into the face. when thrown at a monster, if the monster's challenge rating is less than 2+ the player's level, it has a 1d6 chance of capturing the monster. the monster must be named once captured, and is loyal to the owner of the ball until death, following all commands. to release the monster, the user must say "Go" and the monster's name. to return the monster to the ball, the user must say "Return" and the monster's name. while there is a monster inside the ball, the crystal glows a soft green, if it is critically injured, it glows a soft red, and if the ball is empty it will not glow. if the monster contained in the ball dies the ball will become inert until used on a new monster

Notes: spend one long rest singing how you will be the very best with the ball in hand
