Scion: The Sound of Silence
Perception will act as the linked attribute to damage with firearms, crossbows or any other weapon that shoots a projectile under its own power.
Bows will use either Strength or Perception to damage. Mortal made bows can only add as much Strength as the bow is rated for (very few mortal made bows have a draw powerful enough to make much use of Epic Strength!). Relic bows get ‘stronger’ as the owner does and the draw power will adapt to the user’s strength.
