Classic NV Skill System
Classic NV Skill System is a total overhaul of Fallout 4's lackluster progression system, with the goal of bringing meaning back to character builds.
It restores all 13 classic Skills, all 120 New Vegas Perks, and all 16 Traits. My goal is to make building a character feel important again while bringing that familiar Fallout 3 and New Vegas progression into Fallout 4.
Main Features
-
[]All 13 classic Skills, including Guns, Energy Weapons, Repair, Science, Speech, Survival, and more.[/]
[]All 120 New Vegas Perks integrated into Fallout 4.[/]
[]All 16 Traits, including Wild Wasteland. (Wild Wasteland is currently present but non-functional.)[/]
[]Skill-based damage for Guns, Energy Weapons, Explosives, Melee Weapons, and Unarmed.[/]
[]Skill-based crafting instead of Fallout 4's vanilla crafting perk requirements.[/]
[]Skill-based locks and terminals using Lockpick and Science skills.[/]
[]Skill-based dialogue with configurable Speech and Charisma skill checks.[/]
[]13 temporary Skill Magazines, one for each Skill.[/]
[]Extensive MCM options for Skills, Traits, Perks, progression, and troubleshooting.[/]
[]Patchless comaptibility with KARMA & Condition System Framework (F4SE)[/]

Troubleshooting
If something stops working correctly, use the Refresh options in the MCM before reporting the issue. Refresh All is the best place to start after an update or if something appears missing or stuck.
Load CNVSS as late in your load order as possible, after most other plugins but before PRP.
CNVSS uses Perk Conditions Framework for UI replacements and perk-condition checks. If the problem is specifically related to incorrect requirement text, perk checks, or their UI replacements, please report it on the Perk Conditions Framework mod page rather than the CNVSS page.
When reporting a CNVSS issue, use Write Diagnostic Report in the MCM and include the generated Classic Skill System log whenever possible.
Load Order
Load CNVSS as low as possible, after most other plugins but before PRP.
Credits
Many thanks to ItsMeJesusHChrist for making Consistent Pipboy Icons and its accompanying modders resource. Many icons, both animated and still, would never have been possible without their high-quality source files.
Many thanks to bp42s for being an all-around cool modding friend, playtester, and making various things for me (including the mod page image and a few perk icons). Bp will be maintaining this mod page and directing issues my way to fix should they arise.
Many thanks to Scrivener07 for basically teaching me how to use AS3 in Fallout 4. While Scriv didn't directly assist me with AS3 work on this project, I never would have been able to create an AS3-reliant version of Perk Points Per Level built for NVSS without his previous guidance.
Many thanks to my fellow modding buddies and testers on Greslin's Discord and Collective Modding Discord. Everybody there is really supportive of my modding efforts, and I appreciate that.
Many thanks to Bethesda for making Fallout 4, my least favorite Fallout game. If it was not my least favorite, I never would have started making mods so I'd enjoy it more.
