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
Knowledge Saves
A Knowledge saving throw is made to discern illusions, and to resist trickery or mental assaults that can be refuted with logic or memory.
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.
Attack and Damage Rolls
When you make an attack roll with a studied spell or an alchemical item, you add your Knowledge to the attack roll but add no ability modifier to the damage roll.
For spells, you also add your PB to the attack roll. For items and weapons, you only add your PB if you're proficient with the item or weapon.
Bonus Feats
If your protag’s Knowledge modifier is above 0, you start with a number of minor feats equal to your Knowledge modifier. These are in addition to any feats granted through other features. If your Knowledge modifier later increases (above 0), you gain another minor feat accordingly.
