Backpack of Sharing

The markings on this backpack are unreadable, but the workmanship is clearly that of a master craftsman. 

This backpack holds 1d4 + 3 fanny packs. If you wear a fanny pack, you can acces the backpack through it. This counts as a free action.

The backpack needs to be within 300ft. The backpack can't be accessed directly when a fanny pack is being used, and vice versa.

A fanny pack needs to be attuned to in order to use it. The backpack itself does not.

Notes: Backpack of Sharing, Requires Attunement
