This is my first mod. I recommend running it alongside MorrowLoot Ultimate which you can find here: https://www.nexusmods.com/skyrimspecialedition/mods/3058  for a more challenging experience 

This mod will make your game harder but you will have a better action-based role-playing experience. 
the mod is balanced for normal difficulty.
if you are using version 1 then you need a new game save for version 2. Version 3 is not compatible with 2 due to race changes(skill bonuses were adjusted).

the are 3 versions and a patch:
1) IronMoon - The Roleplaying Overhaul (all in one) - everything in one esp. (version 2, old version)
2) IronMoon - The Roleplaying Overhaul (By Category) - each category is split in its own esp. (version 2)
3) IronMoon - The Roleplaying Overhaul V3 - everything in one esp (version 3)
I will keep 1 and 2 but I will actively update 3rd because it's easier for me to maintain.
4) IM compatibility patch for Ordinator - compatibility patch for "Ordinator - Perks of Skyrim" mod ( for version 3, can be used with version 2)

Races are more like classes from D&D in this mod.

• Redguards and Wood elves are heavy Stamina classes, while Bretons and High elves are heavy magic classes.
• Orcs and Nords are fighters.
• Imperials, Dark Elves, and Argonians are all-around classes with no clear weakness or benefit.
  

Races are impactful as well as birthstone benefits.
