It occurred to me that a particular slanting of the DnD system occurs when you remove magical items- make them less common, remove the monstrous buff spells..
The raw blasting spells become a greater part of the PC damage dealing arsenal. Without magical enhancement bonuses to weapons plus bulls strength plus a belt of strength etc , the fighter only has a few points of attack bonus ahead of the mage. However, the mage is very fragile. Very. Without magical bracers, shield spell etc you are looking at a single digit of bonus.
With magical items the wizard has almost (maybe one more) the same number of spells. Perhaps he gets a caster lv bonus and he most certainly will have a higher stat making saves less likely
