Paper Tubes are collectable items dropped from bosses. Using them in your inventory (the same way as if you would summon bosses) will unlock different accessories for you to buy from Tinkerer's shop.

There are 3 types of Paper Tubes in AlchemistNPC mod, each unlocking certain accessories from different parts of game progression:

  1. Paper Tube (Pre-Hardmode)
  2. Paper Tube (2) (Post-Skeletron - Hardmode)
  3. Paper Tube (3) (Post-Plantera)
