Tool
A tool is a minecraft item enchanted by a rune. Some runes expect a specific tool to activate them, which will be shown in the rune template. If it lists multiple tools, or a category of items, any of the items in that group can be used. Otherwise you can use any item you wish. Recommended is to use an item that cannot be placed. Runecraft will stop you from placing most tools but it can be glitchy.
When activating a tool rune, hold the item in your hand and right-click the middle of the rune.
You can disenchant your items by using Dispel.
