Custom Crafting Menu
The Custom Crafting Menu is the server's own crafting interface, opened by right-clicking a vanilla crafting table. (Sneak while holding an item still places blocks as normal.)
It gives you a 3x3 ingredient grid and an output slot that matches against the server's custom recipes. Shift-click the output to quick-craft and repeat the recipe while you still have ingredients, and any leftovers are handed back when you close the menu. Current recipes include Condensed Crude Ore (a Crude Ore Core plus eight Crude Ore), the Ancient Wand (a Wand Core ringed by eight Wand Components), and the Ancient Bow (a Bow Core ringed by eight Bow Components).
Where to get it: it's built into the server — just right-click any crafting table. See the Recipe Book for what you can make, and Cell Income for how crude ore and forges feed into it.
