Given that a throwing axe is likely to be much more durable than an arrow, and much more findable than a sling bullet, how about reducing the weight of throwing axes to signify their recovery and reuse. Howabout a quarter of the weight, signifying an average of four throws before being lost or damaged?As it is, their weight make them almost unplayable (almost *points up* :p).
Or even better have magical ones that return upon use.
I don't know that I'd agree with this one, for two reasons. First, Layonara (according to the handbook, anyway) is supposed to be a low-magic world, and magic axes that keep coming back aren't really in keeping with that.Second, it'd mean there wouldn't really be any point in making or selling throwing axes, since you'd only ever need one. I like ScriptWrecked's suggestion of making them lighter, though, to reflect one's ability to recover them, and therefore stretch a certain weight of axes further.
*Griff listens eagerly to the discussion*So far I think the best suggestion is the trained throwing axe with unlimited ammo. If their can be trainable bows I don't see why not trainable axes. Maybe the end product would be a stack of 25 weighing 25lbs. The theory being that after the battle, the axes could be retrieved and reused (as has been previously suggested *grins to Argali*).
A possible solution would be be, as Stephen suggested, creating an item which could be used to spawn throwing axes, but this would be prone to abuse.
