Many indigenous people of the frostfell manufacture primitive weapons from bone, wood, sinew, and stone. These weapons, while crude by the standards set by forged weapons, are nonetheless quite effective in skilled hands. Although many of these primitive weapons are categorized as exotic weapons, they can be used as martial weapons by those not trained in their use as exotic weapons. If a primitive exotic weapon is used as a martial weapon, the user cannot make use of any of that weapon's special qualities (such as the iuak's ability to damage objects, or the tigerskull club's ability to disarm and trip). More importantly, primitive weapons are not as sturdy as more modern weapons. When used by someone not trained in how to properly use and care for them, primitive weapons tend to break. Every time a character using a primitive exotic weapon as a martial weapon deals damage over the weapon's normal maximum according to its damage die (such as might result from a high Strength score, using the Power Attack feat, or making a critical hit), the character must make a Reflex save (DC 10 + the damage dealt by the attack) or the weapon breaks and becomes useless. A character with the proper Exotic Weapon Proficiency feat doesn't need to worry about breakage.
