You mean the lvl10 damage enchantment is the only 1 remain at 100 damage even after the new patch, where others rank damage had already being balanced? I not too sure on the latest patch as havent try it out yet. Didnt touch the game much lately. As mentioned earlier, 200 raw damage extra in specs will provide quite some differences in term of damage output.
I havent actually try creating a spell caster before, so no idea if magical damage enchantment will affect spell damage output. But from what I notice, passives like destruction doesnt seem to affect the magical damage portion part of weapon in the status screen.
