The Endless Ichor Dart Box is a Hardmode item that acts as ammunition, and can be placed in the Ammo slots in the player's inventory. While in the user's inventory, it acts as a single Ichor Dart that can be fired from any appropriate Blowpipe, Blowgun, Dart Pistol, or Dart Rifle without being depleted.
Crafting the Endless Ichor Dart Box requires 4 full Ichor Dart stacks (999 each).
The Endless Ichor Dart Box follows the same ammunition priority rules as other ammo types. If held in the inventory, Darts in the dedicated ammo slots will be fired first, followed by those further up and to the left in the player's inventory. While in the ammo slots, those above it will be fired.
The cost of 3996 Ichor Darts is no value. There is no profit in producing Endless Ichor Dart Boxes for resale.
