You would think that any battle-hardened veteran would realize that things
that seem worthless may still have value and that value may be inherent in
those magical properties you don't understand. Furthermore, when fighting a
foe that seems less competent physically than might be expected, might make up
for physical inadequacies with mental or magical potentcy.
So maybe increasing saving for throws against armour/weapon damage for tanks
with this trained quite high (even against dests spells and those pesky
wands).
