Non-casting classes are completely defenseless against golems that spam magic missiles (there's at least one level with hordes of them) for which there is no defense potion (like fire/shock/ice immunity). Only remedy is either invisibility potion or an artifact with reflect magic.
But even a simple wraith that spawns in front of your character will immediately spam numerous fireballs and is a huge threat for a non-caster who cannot simply walk through the entire level invisible and with a reflect magic active.
