Dungeon Tools Mod 1.12.2/1.7.10 adds various tools to help adventure map makers to create dungeons inspired by The Legend of Zelda.
Locks & Chains: Any lock block that is right-clicked with the right key will disappear, along with any connected chain blocks of the same type.
Ground Item Block: Right-click this block with any item to put the item on the ground! You can rotate the item by right-clicking using a clay ball. (These ?blocks? can then be right-clicked by a player in survival/adventure to pick up the set item.)
Hard Web: A solid web block. If right-clicked with a Lantern (see Items) it will burn itself along with any connected hard web blocks.
Unlit Torch: Right-click with a Lantern to relight the torch!
Keys: Can be used to unlock the desired door type.
Lantern & Oil: The Lantern can be used to relight torches and burn hard web. Put oil in the crafting grid to fill up the lantern.
Written Note: A purely cosmetic clone of the Written Book. This item has no book cover, it only acts as a page. (To fill in text on the pages use the NBT Transfer tool (also included in the mod) to transfer the text from a Written Book to the Written Note.)
NBT Transfer: Right-clicking will transfer the NBT Tag from the leftmost item in the hotbar to the rightmost item in the hotbar.
