@cryum : not really, right now he is in desperate need of income, and working as a porter is the only real option, plus his other cheats benefit from it.
There is no real safer option, since in a society of this level a job outside the adventurers guild would be almost impossible, and a porter for a party is his best option. If the party can keep their spellcasteds safe, they can keep him safe since he will only be evading.
There is also a time factor, since the kingdom could decide to eliminate him at any moment This is not guaranteed, but there are to many possible reasons for them to decide to if even just to cover up part of the summoning.
Plus if he needs the drops then there us a real chance he needs to go out to the field, as the adventurers are likely only taking back parts of their kills (as unless every part us just as valuable, and they are not getting paid a bounty for proof of kills, they will just take the parts with the best value to weight ratio so they can maximize their payout), so the drop items might not be an option if he was not there.
There is safe and necessary risk, being a porter is basically a necessary risk for future safety.
