📋 About This Mod
ia8M8h97GAc
Classic NV Skill System replaces Fallout 4's perk-based progression with skills and perks inspired by Fallout 3 and New Vegas.
Skill Perks: Perks such as Locksmith, Hacker, Sneak, Medic, etc. are no longer available. Instead, proficiency is handled automatically as their related skill increases.
Crafting: Crafting is no longer controlled by Fallout 4 perk ranks. Instead, crafting requirements are based directly on your skills. Repair is the skill most closely tied to crafting and is used for most weapon and armor modifications, while other skills such as Barter, Explosives, Science, Medicine, and Survival cover their own related recipes.
Combat: Weapon proficiency scales directly with your skill level. Guns, Energy Weapons, Explosives, Melee Weapons, and Unarmed become stronger as you invest points into them rather than relying on perk ranks.
Compatibility: The latest 2. 0 update was made with compatibility in mind. The new UI integration should be compatible with most UIs and resolutions and has confirmed compatibility with both DEF_UI and FallUI. 2. 0 also includes patchless KARMA compatibility for the three Lonesome Road KARMA perks, along with a new API that allows mod authors to check CNVSS skill values and perks without requiring CNVSS as a hard requirement.
