Notes

• Catalysts generally scale with Intelligence, and therefore this can lead to stronger spells

• Lack of Intelligence to wield a weapon or shield (as shown with the red X on the D-pad menu) doesn't make the character have a different animation like Strength does, but the weapon still gets the damage penalty and bouncing attacks

• On catalysts and Velka's Talisman, it just makes them unusable

• In addition to the equipments listed above, equipments in Magic and Enchanted upgrade paths also have Intelligence scaling for Magic damage

• Pyromancy Flame has an Intelligence scaling listed. This scaling, however, does not affect its damage whatsoever.
