F/p Arch mage and bossing

The snail works for the entire party iirc, so giving one to someone in your party who has high status resist could work if you go with the same group often. Aside from that mages can only really raise their own status resist.
[MENTION=8585]valhala556[/MENTION]; shadowers get 60% damage reduction and passive 45% dodge plus naturally high avoid, not sure how much HP/avoid one would need to be trollier than a paladin (don't they get divine shield too btw?).

It isn't damage reduction, it's damage redirection -- it works the same way as magic guard, but with money. A 1/1 still brings a shadower's HP down to 1.
