Hello, I got that mission from the job board :
I tried to bring him a limb, some fine leather, meat, a serpentskin helmet...
But the answer is always
I'm near the end of the game and killed most of the monsters that could be found in the game, even the dragons & drakes (bad, bad Roberto) so I really have no idea what I'm supposed to bring to that goddamn Arbuckle mayor (is he related to Garfield ?)
Any help would be welcomed !
