Knowledge (or “Intelligence”) is one of the six ability scores.

Knowledge measures logic, memory, and the capacity to learn.

Knowledge Checks

A Knowledge check can model any task that draws primarily on information your character might have learned—whether through education, rumors, or personal experience. A Knowledge check can also model deductive reasoning or complex mental problem-solving, such as with the Deduce action. Possibilities include:

  • Recall lore about the world, its inhabitants, and its history
  • Identify facts about spells, extraordinary creatures, deities, the afterlife, or other supernatural phenomenon
  • Craft or repair an item
  • Search for clues and make deductions based on those clues
  • Discern from a wound what caused the damage
  • Understand foreign languages or ancient scrolls
  • Appraise an item and estimate its value
  • Win a game of strategy
  • Forge a document
  • Identify secret signs or subtle clues
  • Play a well-recited number with a musical instrument, as opposed to creating or improving new music

Will Saves

The higher modifier between your Knowledge and Charisma is added to your Will saving throws.

Knowledge Mark

Your Knowledge mark equals: 8 + PB + Knowledge modifier.

If you learn spells through study or memorization, saves made against them are made against your Knowledge mark. Similarly, any saving throw made against an alchemical item you use is made against your Knowledge mark.
