idk I always started my flesh like casters with 8 str. It can suck in the starting levels but im usually outa there and into max gear anyway. My caster has a +6 str item, a +2 tome, ship buffs, rage, and I got em 3 piece abashi set.
End game I really never even see enfeeblement cast. Usually it's that flippn 5 or 8 levels gone in a single hit drain that I worry about. Always carry a slew of restorations with ya.
