Enchanting values leveled out a bit.
20-skill enchanter can make enchantments about on par with basic enchanted items (which are usually half as strong as peerless ones),
75-skill enchanter can make enchants about on par with peerless enchants,
master enchanter can make enchants that are relatively competitive with artifacts as Law of Firsts has been buffed and master level enchanting provides additional enchanting power. However, enchanters still won’t be able to make items on par with the mightiest artifacts as they lack the ability to put half a dozen individually powerful enchantments on high-end items.
Soul Gem Mastery works like in AZtweaks, allowing you to get proportionally more use out of
low-end soul gems.
Overall enchanting is quite a bit buffed over vanilla Requiem but it was fairly weak to begin with
and it no longer generates XP on its own due to the new skill system.
Player made enchants are also worth a bit less to prevent the player from getting too much
trade fodder.
