Broadhead arrows are some of the deadliest arrows available. They inflict moderate amounts of edge damage and can easily cause serious, bleeding wounds from afar. One of the downsides to these arrows is that they are almost guaranteed to damage the hides of animals and, for this reason, should be reserved for combat against humans and hunting only the very largest animals.
While deadly in combat, more types of clothing and armor resist the edge damage dealt by broadhead arrows and they can simply bounce off of a more heavily armored opponent like a Njerpez warrior wearing lamellar and mail.
These are rare arrows that can not be crafted, only acquired through trade, theft or combat.
