Bag of Brambles

A worn pouch kept together by old threads, even touching the outside the sharp thorns can be felt trying to poke through, keeping curious hands out of your heavy pockets. 

The bag acts as a pouch and can be used to contain small items, such as coins, rings and other small trinkets. If the item inserted is fragile, such as a potion in a glass bottle,  it shatters instantly when placed into the pouch.

The creature attuned to this pouch can use the pouch freely. A creature attempting to place or remove an item from the pouch when not attuned to the item must make a strength saving throw with a DC of 14 or become entangled (restrained) by the bag, moving with it, and have their limb trapped within the pouch by brambles and vines. The vines can be burnt and destroyed but are restored and regrown at the end of a long rest.

A command word of the wielder's choice may be used to attempt to restrain a grappled or prone creature using the bag once per long rest, acting as a rope or binding, and a different command word removes the vines from an entangled creature.

Notes: Restrained, Short rest spent investigating the item - not needed if the character is a ranger or druid
