In Minecraft, tools can be repaired by anvils. The same goes for most of the tools in Divine RPG. However, due to the mechanics of the mod, although items may be repaired, they may not necessarily be repaired by the materials that they are made out of. Combining a tool with itself (e.g. Repairing a Diamond Shovel with a Diamond Shovel) is not considered to be a repair.
If a "repairing material" cannot be found for a particular tool, it will be marked with "Unknown". If a tool has Infinite Uses, then they do not need to be repaired ,and hence will be marked with "N/A". Below are tables listing all the tools introduced in Divine RPG (still in development), and what they can be repaired by.
Tools can also be classified in terms of whether or not they are worth repairing. For example: A Diamond Shovel is crafted with 1 Diamond, but requires a total of 4 Diamonds to repair it completely. Therefore, it is much better to craft a new Diamond Shovel, and hence it is not worth repairing. Figures will be displayed in the form of "Repairing Cost" to "Crafting Cost". This classification assumes you have not put any enchantments on your weapon.
