KOBOLDS

Kobolds are a mobfaction that scales in strength and number according to
the average level of the players in a trade run formation. Kobolds will
spawn along either side of the trade route and fire arrows at the trading
formation. If they are not killed, all the kobolds will ambush the
formation at once and attempt to overwhelm you with their numbers. Proceed
with caution!
