Tested the cooking pot, didnt seem to add much if any at all. Damage was the same with eagle shield M attk lv 2 and Obli Alteration lv17 max (52 max)
So I guess try the test again with overature and see how much it adds? Btw, finished re-enchanting my circlet, it's now oblivion dexterity. I'll try again with food buff and magic potion but I did crit 23k on Saga 2 Ruairi form 2.
