Skills and Abilities
Skill Abilities
Skill abilities are abilities your character unlocks by reaching certain (even) levels in skills. Check the section of this guide for each skill to see the abilities it provides.
Spell Prerequisites
Reaching certain (odd) levels in skills can unlock new spells and spell enhancements. You only gain new spells and spell enhancements from Arts that you know (see Spells and Traces for more information about learning Arts). Check the section of this guide for each Art to see what you can unlock, and what skills you need to unlock them.
Temporary Skill Changes
Some effects temporarily increase or reduce your skills. You retain any unlocked skill abilities even if the relevant skill is reduced below the required value for that perk, and, similarly, do not unlock new skill abilities from temporary increases. Skills cannot be increased above 9 or reduced below 1 (if they ever would be, they instead change to 9 or 1 and the rest of the increase or reduction is lost).
Skill Costs
Some abilities will require you to temporarily lose points in a skill in order to use them (e.g. "lose 2 Arcana to..."). You cannot use these abilities if the loss would reduce your score in that skill to less than 1. Some abilities cause your score in a skill to fall to 1. You cannot use these abilities if your score in that skill is already 1.
