1. If the initial attack roll is within the critical threat range, and is 5-9 higher than what was necessary to hit, a Mild Critical Effect has occurred.
2. If the initial attack roll is within the critical threat range, and is 10-14 higher than what was necessary to hit, a Moderate Critical Effect has occurred.
3. If the initial attack roll is within the critical threat range, and is 5-9 higher than what was necessary to hit, a Severe Critical Effect has occurred.
4. Determine the creature’s body profile (i.e. humanoid, four-legged beast, etc.). These should be listed with the encounter information below.
5. Look up that body profile in Torn Asunder (page reference should be included in the encounter for quick reference), and randomly determine where the critical effect landed (i.e. head, arm, leg, wing, etc.).
6. Whatever the effect is for that severity and location takes place. For example, a player rolls to attack a four-legged beast and the roll is within the critical threat range, and it is 12 over what was needed to hit. Looking up “Four-legged beast” in Torn Asunder (page 13), we see that you roll a d8 to determine where the hit landed, say Leg (C). Since it was a Moderate Critical Effect, you look on the following couple pages for Leg (Appendage) – Moderate and discover that the creature’s movement rate is reduced by 1⁄2, etc.
7. Also, feel free to remind players that there is a called shots system incorporated into this critical hits variant. Encourage them to give that a try as well.
