This is super outdated for requiem 4, y'all are now on requiem 5. Feel free to download it and see how to edit it yourself but this won't be updated to 5.x in all likelihood.


Vanilla atronach stone: +50 magicka, 50% spell absorption, -50% magicka regen mult (the same thing you would find on, and therefore easily reversed with, novice or higher robes)

Requiem atronach stone: +350 magicka, 50% spell absorption, -10000% magicka regen mult (reversible through extreme enchanting exploits? either way makes robe enchants otherwise worthless), lowers magicka from potions by 33%, sets duration to 0 on health/stamina/magicka/carryweight related food buffs and removes magicka restoration from food out of combat.

Requiem-SAS atronach stone (this mod): +300 magicka, 60% spell absorption, -0.98%/second base magicka regen (applies to all conditions, allows racial differences in requiem to have drastic impact and robes to work again), lowers magicka from potions by 70%, sets duration to 0 on magicka related food buffs and removes magicka restoration from food out of combat.

Races base magicka regen/second % of max magicka (subtract 0.98% with stone, unchanged): 
Vanilla: 3%/s all races
Requiem:
1.00%/s: Khajiit / Orc / Redguard (2% of normal regen with atronach stone)
1.05%/s: Nord / Wood Elf (6.66%)
1.10%/s: Argonian / Dark Elf / Imperial (11%) (about 2.5 hours to restore 400 magicka)
1.15%/s: Breton (15%)
1.25%/s: High Elf (22%)
