Bag of Safe Holding

This bag has an interior space considerably larger than its outside dimensions. The bag weighs 15 pounds, regardless of its contents. Retrieving an item from the bag requires an action.

Safety against meddlers and wrongdoers

• Attempting to pierce, tear or otherwise damage the bag, pull it inside out, or searching without knowing its contents requires the offending creature to roll a charisma saving throw to be able to attempt the action, taking psychic damage and wasting their action or attack on a failure, half damage on success. Upon succeeding this saving throw, they need to succeed on a strength saving throw, being pulled into the bag on a failure. Succeeding on the charisma saving throw makes a creature immune to the damaging effect for 1d8+2 minutes. Succeeding on the strength saving throw makes a creature immune to the pulling effect for 1d8+2 minutes. Attempting to exit the bag requires an acrobatics or athletics check against the bag's save DC.
• Attempting to put this bag inside a bag of holding, Handy Haversack, portable hole or similar extradimensional storage causes the same protections to trigger as attempting to damage the bag, however the offending creature being trapped in the Bag of Safe Holding causes this item to not enter the other magical storage.

Safety for recursive storage attempts

• Attempts to store a bag of holding, Handy Haversack, portable hole or similar extradimensional storage item in an uncommon bag of safe holding always fail, this item will reject those.
• Attempts to store a bag of holding, Handy Haversack, portable hole or similar extradimensional storage item in a rare or higher bag of safe holding require a charisma saving throw, the user taking psychic damage and the bag rejecting the item on a failure. A success causes the user to take half damage and the item to be stored safely.

Safe storage of storage

• A bag of holding, Handy Haversack, portable hole or similar extradimensional storage item stored within a rare or higher bag of safe holding are deactivated as they start entering the bag of safe holding.
• Deactivated extradimensional storage items are reactivated 1d8 minutes after fully exiting the bag of safe holding.
• Deactivated extradimensional storage items of a rarity lower than the bag of safe holding they are stored within become nonmagical and their contents scatter across a random plane or demiplane after 1d8+24 consecutive hours of being deactivated.

There's a limit to safety

Successfully putting this bag inside a bag of holding, Handy Haversack, portable hole or similar extradimensional storage causes the normal effect for putting a bag of holding inside said extradimensional storage.
