SerqFeht is right, Dakrru's Curse (the death curse I call it) would make the stats more like this:
Agility: 100 (200)
Charisma: 54 (108)
Endurance: 65 (130)
.
.
.
cutting your stats in half, until the curse expires.
even if Strowtripper accidently reversed his posting of Strength: 175 (160), Dakrru's Curse is not it.
on the supposition that his order is correct, he's got something augmenting his strength. if not something is diminishing it, either way, check weapons, armor, rings, etc.
