[Ziggurat]

My throwing ability goes up using the sling, so you can always use that as an alternative but it's not two-handed. I seem to get more "crit"-type ranged hits (including unconsciousness) as I go along in the game (even the bishop). Of course, the ammo gets better so I may be partly deceived. But at least it doesn't run out like most thrown objects. Use the thrown objects using 2-hands, switch to sling til you get more, switch back, etc.
