Brittle Bones (D)

Your bones are brittle.

You suffer 50% more damage from blugeoning attacks, falling, and other sources of concussive damage.

Brittle Bones (D) is a physical defect that causes the player to take extra damage from certain damage types.

If the player receives fall damage, such as when falling down a deep shaft, damage from cudgels, or concussive damage, such as that dealt by Stunning Force, the total damage dealt will be multiplied by 1.5.[1] The message log will also return the following message:

You feel your bones fracture.

Advantages & Disadvantages

This section is opinion-based. Your mileage may vary.


  • Grants 4 extra points to use during character creation
  • Only affects sources of blunt damage


  • Can make enemies that deal the affected damage types extremely dangerous
  • Enemies dealing cudgel and concussive damage can often stun the player, making stun-locking even more deadly
