Bag of Kittens

This bag is a portal to an extradimentional kitten paradise. Its interior is a divinely designed cat condominium that comfortably houses 1,000 magical kittens. The kittens to not need to eat, drink, or breath, and will always return to the bag unharmed when the effect ends. The kittens cannot be harmed, any creature who attempts to harm a kitten takes 2d8 psychic damage and becomes frightened of cats for 1d4+1 days.

The bag has 3 charges, and regains one charge at dawn every third day. If you use all three charges, roll a 1d20. On a result of 1, the kittens are overtired, and the bag does not regain a charge for 2 weeks.

Fluffball. As an action, you can reach into the bag and throw a kitten at a creature within 30 feet of you that you can see. The creature must make a Dexterity saving throw (DC = 10 + your proficiency bonus + your Dexterity modifier). On a failure,  the creature is grappled by the kitten for 1 minute, scratching and distracting it as it attempts to climb the target like a scratching post. On a successful saving throw, the effect ends and the kitten returns to the bag.

At the start of each of its turns, a grappled creature takes 1d6 piercing damage. The creature can attempt to end the effect by making a Dexterity saving throw (DC = 10 + your proficiency bonus + your Dexterity modifier) as an action on its turn. 

Purrfection. As an action during a short or long rest, you can remove any number of kittens from the bag. The kittens are unbelievably cute, playing happily with you and your allies until they tire. The kittens then curl up with whoever wants them and nap peacefully, fading back into their bag after one hour. A creature who enjoys the company of one or more kittens during a short or long rest gains temporary hit points equal to 2d8 + your Charisma modifier. These temporary hit points are always used first, and last until the end of your next long rest.

A Thousand Tiny Claws. As an action, you can turn the bag inside out, releasing all 1,000 kittens in a 15-foot radius around you. The area becomes difficult terrain as enemies attempt to step around the kittens without hurting them. At the start of each of your turns, you must make a Wisdom saving throw (DC 10) to avoid becoming fixated on cuteness, and maintain concentration (as if with a spell). If you fail this saving throw, the kittens fade back to their home plane inside the bag.

Each hostile creature that starts its turn within the kittens must make a Wisdom saving throw (DC = 10 + your Wisdom modifier + 5 for cuteness). On a failure, a creature takes 2d8 piercing damage from hundreds of tiny claws, has its speed reduced to 0, and makes all attack rolls, ability checks, and saving throws at disadvantage until the start of your next turn as it is distracted by the waves of adorable kittens. On a success, a creature takes half damage and suffers no other effects.

The kittens return to the bag after 1 minute, if you lose concentration, or if you dismiss them as an action.
