The Napsack is a Fight Tab Item exclusive to Don't Starve Together, introduced in A New Reign. To prototype it, players need its Rare Blueprint dropped by the Misery Toadstool. Four Napsacks can be crafted using a Shroom Skin and a Poisoned Canary.
- "Napsack" is a portmanteau of the words "nap" and "sack".
- The Napsack was added in an unnamed Bonus Update after the completion of A New Reign.
- A "Knapsack" (or "Napsack") is a sack-like strapped carry-on, similar to a backpack.
- Napsacks can be used to duplicate Shroom Skin by using a Deconstruction Staff, since four Napsacks are made each batch. Since Green Gems are renewable through Tumbleweeds and Ruins regeneration, this can be used to mass-produce Shroom Skins from at least one skin.
