last night i reached level 100 enchanting
i hadn't spent a single perk in enchanting untill level 100 enchanting
i gathered a couple of filled black soul gems i had stored away and bought about 2 more + a mage hood
I then set out to white run and bought a blue mage robe and a silver ruby ring and a silver necklace with 3 gems in it (not that item type matters too terribly much when comes jewlery...)
1st i enchanted the hood with 25% fortify destruction and 25% fortify illusion i then stuck those same to enchants on the ring and the amulet thats a total of 75% destruction and illusion reduction
now on the mage robe i stuck 25% fortify destruction but i also added 15% fortify destruction + 10% magicka regen
thats a total of 115% reduction to the cast charge of all destruction magick
so i can run laps around winterhold college and never run out of manna freezing the place solid with ice wall
i can also potentially when i get level 100 destruction infinitatly cast the lightning spell
so what was the alchemy/enchating "exploit" supposed to have been for ?
