on ranging the kbd: do note that the crystal bow keeps over any item,(idk about the dragonfire shield) ava's attractor is very handy when using any projectile, it even gives a range bonus(it's better than everything but a firecape) if you reccomend using ruby tipped bolts, they need normal addy or diamond tipped bolts to switch to, as blood bargain loses effectiveness when the kbd is really low on hp. someone should also be using a few emerald tipped mithril bolts if nobody is using a dds
