I would have imbued the balls with Ballistic Enchantment as well. Another plus 22% Range. Not to mention with how many unique targets you'll likely be hitting with them at that size, Id expect it would give massive weapon damage. And of course there is always your old friend Trophy Collector
Incredibly silly idea and I haven't tested it yet but: Stealth Silver. Shadow Weave and Veil Walker, skulk around the map and ambush people. No idea if it'll work but I'd figured I'd throw that out.
