Intelligence (PSR Supplement)

---

Intelligence is one of the six ability scores.

Intelligence measures mental acuity, accuracy of recall, and the ability to reason.

Intelligence Checks

A Intelligence check can model any task that draws on your logic, knowledge, education, memory, or deductive reasoning—including the Search 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 glues
• Discern from a wound what caused the damage
• Understand foreign languages or ancient scrolls
• Appraise an item and estimate its value
• Eavesdrop on a conversation in a noisy street
• Win a game of strategy
• Forge a document
• Follow tracks
• Identify secret signs or subtle clues
• Play a well-recited number with a musical instrument, as opposed to creating or improving new music

Intelligence Saves

An Intelligence save is made to overcome illusions or other magical trickery that affects the mind. Such saves can be made for mental assaults that can be refuted with sharp memory, logic, or both.

Intelligence DC

Your Intelligence DC equals: 8 + PB + Intelligence modifier.

If you learn psionics, or spells through study and memorization, saves against them are made against your Intelligence DC.

Attack and Damage Rolls

Attacks with artillery adds your Intelligence modifier to the attack roll, but no modifier is added to the damage.

If you make an attack using psionics or a spell learned through study, you add your Intelligence modifier to the attack roll alongside your PB, but no modifier is added to the damage.

Proficiencies

Your Intelligence may affect how many skill, tool, languages, or other proficiencies you have as detailed in your class or character creation.

If after character creation your Intelligence increases to the next threshold to gain another one of these proficiencies, you gain the corresponding proficiency. If your Intelligence later falls below that threshold, you lose that proficiency.
