This patch makes Skyrim Immersive Creatures Compatible with Requiem Version 3.20 and 3.3.0. It will NOT work with earlier versions.
Before doing anything Install SIC and SIC official patch that can be found here.
Now there are several things you need to know:
1. Make sure that Extended armor feature in mcm menu is turned off. It replaces requiem armor values and messes with armor penetration system which can but doesn't need to lead to significantly easier enemies.
2. I strongly suggest you to disable extended stats option as well, in theory it shouldn't clash with anything but i haven't tested it enough to say it for certain.
3. Leave Global Difficulty on adept, changing it will not affect creatures and their strength but will affect their damage taken so you will either get Draugr that you easily one shot at level one or god mod that can't be killed at all. Remember 1.9.4 patch if you played it.
Now with that being said i'll say a few words, a few only mind you i took me well over a month to make this and explaining everything would take just as much.
The patch is fully deleveled, which means there are no leveled creatures left.
I made it fair as much as i could. The creatures' strength was based on their spawn points, so sensible challenge will await, Giant tundra spider for instance was made to be perfectly possible at sub 10 levels but it's strength remains the same as of their frostbite cousins. Let's call it an intersting fighting mechanic.
In addition some crashes that i found like corrupted meshes and the like have been fixed to the best of my ability. I am not allowed to fix that problem myself so i just removed them from the leveled lists, so the creatures won't spawn anymore.
Leveled Lists and creatures have been properly assembled. You won't get some nonsense like Dragon priest in BFB. Undesirables have been weeded out.
Draugr do not have armor problems in case you are wondering.
The creatures won't drop overpowered items anymore and their inventory was carefully balanced. The point of this mod is creature variety after all not free loot.
In some cases AI was altered to make it plausible. No more Wolf pups rushing at you and such.
Many other things I'll leave for you to discover.
