So we all know Fighters can't have nice things, even in games were the magics are blasting instead of dictating physics.
But I've been thinking of a simple DR buff that I feel would make the gap between mundane and magic slightly less in those cases.
Simply: Magic does not automatically overcome DR, it must deal the appropriate type of damage. Spells with an alignment component overcome DR as that alignment.
Then, in case anyone wants to complain, give them a metamagic feat to apply damage type to their spells. Tier 1 with +0 SL, Tier 2 with +1, adamantine, aligned with caster, and exotic with +2.
And of course, now DR/- actually stops all damage.
