Mods are used to improve the characteristics of weapons, tools, armor and vehicles. They can be mounted in the mod slots of the aforementioned items. The number of slots varies by quality between 1 and 4. Mods increase item damage (Both Entity Damage and Block Damage when added, 10%[1] for items only having 1 slot which gets lower for each available slot. While per item damage increase decreases, the total damage increase increases. When added to weapons mods give 300 increase to economic value. On the following lists, mods are categorized based on their main usage. The division between weapon and tool mods reflects the overall impact the mods have on items. Most of the mods can be applied to both weapons and tools. More specific information about where a mod can be mounted can be found on the mod's page.
