Mods are used to improve the characteristics of weapons and tools. They can be mounted in the mod slots in various weapons, tools and armor. The number of slots varies by quality between 1 and 4. Mods offer 10% damage increase when added to weapons and 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.
