Make and / or distribute Crossbows
With the availability of the IDE Arrows (Brilliant, BTW!) and Bolts, I see you are also carrying bows - this is a very good start! You have Crossbow bolts, but it seems LARP-safe Crossbows are hard to come by - the only decent ones I've seen were by Arrow Kaster out of Europe, but they went out of business a while back. No one today makes good, 25 pound draw Crossbows that would look good and be safe in a LARP, even with the bolts being available.
