Torches are the basic supply of light in Minecraft, and the very first light-source you might get your hands on. In this mod, however, torches run out, and must be re-lit by a lighter in order to keep on making light.
An Unlit Torch is a torch that is crafted exactly like the standard vanilla torches, but they must be lit by a lighter.
LitEditLit torches behave exactly the same way as regular vanilla torches, but they only stay on for a limited amount of time, whether they are on a block or your inventory.
Torches and lanterns, when they are being held, will illuminate light around you much like they would on a block.
