Introduction
TTR.S.O. is a minimalistic and modular skill overhaul aimed at balancing the vanilla skills while maintaining the vanilla feel. Magic, Combat and Stealth skill trees have been balanced to offer meaningful choices with perks, spells and some mechanics.

If you feel the vanilla Skyrim was doing a "good" job but was just missing something, this mod is for you. Overall, the game is gonna be a bit harder since I've fixed a lot of exploits, but it won't be overwhelming nor will prevent you from becoming a legend.

Each skill tree has its own ESP file so you can activate only the ones you want. For a description of almost all the changes made by this mod, you can consult the image section or the HTML version of this page. Highlighted parts show what changed from vanilla Skyrim. Notes are always new changes so I didn't highlighted them to avoid color oversaturation. Perks not present anymore in the skill trees have been modified to reflect the perks they have been replaced with. This will allow NPCs to benefit from those perks the same way you do yours.

2018-04-16: A new merged version with all DLCs is also available! Thanks Will58448

Installation and Requirements
-- Requirements --

• Latest version of Skyrim
• (optional) Dawnguard
• (optional) Dragonborn
• (optional) Heartfire
  

-- Install (auto) --
For an automatic install without risk of errors, I suggest you use the NexusModManager. Simply select the DLC you use, if any, click "Next" and select the skill trees you want to install.

-- Install (manual) --
For a manual install, extract the files from this mod and copy them to the appropriate folders. The important thing to remember is that each ESP is complete by itself, meaning you only need 1 ESP perk skill.

If you don't have any DLC, you should remove all files with suffixes (_DB, _DBDG, _DBDGHF, _DBHF, _DG, _DGHF, _HF).

If you use one or more DLCs, it's a bit more complicated as you need to keep the ones that "applies" to your situation. Each DLC has a suffix associated with it (DG:Dawnguard, DB:Dragonborn, HF:Heartfires) and you need to eliminate the ESPs you can't use by keeping the only file that match the right suffixes. For any combination of DLCs, there is only 1 ESP possible. If a skill doesn't have any ESP with the suffix for your DLC, that means the DLC has no impact on it and thus don't need to be part of the suffix for that skill.

When all is said and done, I suggest you remove the suffixes from the ESPs you install, meaning that "TTR_Skill_Overhaul_Sneak_DB.esp" would become "TTR_Skill_Overhaul_Sneak.esp". This will ensure a smoother upgrade to newer versions.

-- Built-in install/reset/uninstall quest --
There's a built-in quest to manage installation, reset and uninstallation of each module (ESP and ESM).

The first time you load your game, the install phase will automatically start after 5 seconds. Then, the reset phase will begin and each skill tree will be reset, giving you back all your perk points.

This will happen only once and it's necessary to have all the right settings. If a new version need some initializations, it will automatically reset only the required skill trees when you load your game the first time after an update.

If you want to manually reset a module to get back your perk points, open the console and type SetStage TTR_Reset_Module 50. Simply replace "Module" with the module you want to reset (Alteration, Archery, etc.). This can be done as many time as you want and you can find all the required commands in the TTR_Reset_Module.txt file included in this mod.

As a precaution while a module installs/resets itself, it would be wise to wait until the messages stops before doing anything.

The uninstall quest will be detailed further down.

-- The problem with Legendary skills and Dragonborn's "reset perks" option --
Unfortunately, legendary skills and Dragonborn's "reset perks" option don't reset everything correctly, even for the vanilla perks. You get back all your perk points, but some things aren't reset like your higher chance to find special treasure with Treasure Hunter. This means that after picking Tresure Hunter and use any of those 2 options to get back your perk points, you don't have to invest in this perk again to benefit from it... That's one of the reason why I included a built-in reset quest. Unfortunately, I couldn't reset everything either, but I take care of much more things than those 2 options do on their own.

To force a clean reset after using legendary skills or Dragonborn's "reset perks", simply save and reload your game. The reset quest will automatically start after 5 seconds, even if you used quick save/load functionality. If you don't want to save/reload, simply launch the reset manually with the console.

-- Uninstall --
To remove all traces of this mod from your save game (even the scripts), load your game and open the console. The command to launch the built-in uninstall quest is the same as with the reset quest, but you will use a stage of 100 instead of 50 (SetStage TTR_Reset_Module 100).

Do not forget to uninstall the ESM module, it's very important.

When you're done, save your game in a new slot, quick saves won't work.

Finally, close your game and use the uninstall function of the NexusModManager or manually delete all the files of this mod. Be sure you're not in The Frozen Heart inn (Winterhold) when doing so because there's a custom merchant there.

If you change your mind after uninstalling my mod, you can re-install it following the "install" section and then launching the built-in install quest. While the reset quest used stage 50 and the uninstall quest used stage 100, the install quest use stage 0 (SetStage TTR_Reset_Module 0). Quite simple isn't it?

If for any reason you have a problem after uninstalling this mod, try to install the ESM module only and this should solve the problem. I'm pretty confident this won't be necessary.


Compatibility

• Obviously, this mod will conflict with other perk mods. Fortunately, this mod is modular so you can decide which modules you want
• Ace - Combat Skills: There's a weapon speed fix included in the "Melee" module that will conflict with my mod. To disable ACE's weapon speed fix, simply open the console and type "set WeaponSpeedBaseFix to 0"
  

Future plans

• none
