Recognize Spell 
Feat 1
Source Pathfinder Core Rulebook
Prerequisites trained in Arcana, Nature, Occultism or Religion
Trigger A creature within line of sight casts a spell that you don't have prepared or in your spell repertoire, or a trap or similar object casts such a spell. You must be aware of the casting.
If you are trained in the appropriate skill for the spell's tradition and it's a common spell of 2nd level or lower, you automatically identify it (you still roll to attempt to get a critical success, but can't get a worse result than success). The highest level of spell you automatically identify increases to 4 if you're an expert, 6 if you're a master, and 10 if you're legendary.
The GM rolls a secret Arcana, Nature, Occultism, or Religion check, whichever corresponds to the tradition of the spell being cast. If you're not trained in the skill, you can't get a result better than failure.
Critical Success You correctly recognize the spell and gain a +1 circumstance bonus to your saving throw or your AC against it.
Success You correctly recognize the spell.
Failure You fail to recognize the spell.
Critical Failure You misidentify the spell as another spell entirely, of the GM's choice.

Reveal True Name 
Feat 1
Source Pathfinder Secrets of Magic
Prerequisites trained in Intimidation, trained in Arcana, Nature, Occultism, or Religion
You attempt to get a creature to do as you wish by threatening them with your knowledge of their true name. You must know and speak the creature's true name and say what you want the creature to do. Attempt an intimidation check against the target's Will DC.
Critical Success The target does as you say out of a sense of self-preservation, and will not harm itself in any way. It becomes unfriendly (if it wasn't already unfriendly or hostile) but continues to comply for up to 1 day. The target is too scared of you to retaliate or flee, certain you would find them wherever they might go.
Success As critical success, but once the target becomes unfriendly, they avoid you and might act against you in an indirect manner, such as alerting your enemies to your location.
Failure The target refuses to comply and typically flees your presence to avoid your further use of their true name. If they were not already unfriendly or hostile, they become unfriendly. They avoid you in the future and are likely to take indirect action against you.
Critical Failure The target refuses to comply and becomes hostile, if it wasn't already. If they perceive you as weak, they might attack you; otherwise, they likely flee to avoid your further use of their true name.
Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
AuditoryAuditory actions and effects rely on sound. An action with the auditory trait can be successfully performed only if the creature using the action can speak or otherwise produce the required sounds. A spell or effect with the auditory trait has its effect only if the target can hear it. This applies only to sound-based parts of the effect, as determined by the GM. This is different from a sonic effect, which still affects targets who can't hear it (such as deaf targets) as long as the effect itself makes sound.
ConcentrateAn action with this trait requires a degree of mental concentration and discipline.
EmotionThis effect alters a creature's emotions. Effects with this trait always have the mental trait as well. Creatures with special training or that have mechanical or artificial intelligence are immune to emotion effects.
GeneralA type of feat that any character can select, regardless of ancestry and class, as long as they meet the prerequisites. You can select a feat with this trait when your class grants a general feat.
MentalA mental effect can alter the target's mind. It has no effect on an object or a mindless creature.
SkillA general feat with the skill trait improves your skills and their actions or gives you new actions for a skill. A feat with this trait can be selected when a class grants a skill feat or general feat. Archetype feats with the skill trait can be selected in place of a skill feat if you have that archetype's dedication feat.
Trick Magic Item 
Feat 1
Source Pathfinder Core Rulebook
Prerequisites trained in Arcana, Nature, Occultism, or Religion
You examine a magic item you normally couldn't use in an effort to fool it and activate it temporarily. For example, this might allow a fighter to cast a spell from a wand or allow a wizard to cast a spell that's not on the arcane list using a scroll. You must know what activating the item does, or you can't attempt to trick it.
Attempt a check using the skill matching the item's magic tradition, or matching a tradition that has the spell on its list, if you're trying to cast a spell from the item. The relevant skills are Arcana for arcane, Nature for primal, Occultism for occult, Religion for divine, or any of the four for an item that has the magical trait and not a tradition trait. The GM determines the DC based on the item's level (possibly adjusted depending on the item or situation).
If you activate a magic item that requires a spell attack roll or spell DC and you don't have the ability to cast spells of the relevant tradition, use your level as your proficiency bonus and the highest of your Intelligence, Wisdom, or Charisma modifiers.
If you're a master in the appropriate skill for the item's tradition, you instead use the trained proficiency bonus, and if you're legendary, you instead use the expert proficiency bonus.
Success For the rest of the current turn, you can spend actions to activate the item as if you could normally use it.
Failure You can't use the item or try to trick it again this turn, but you can try again on subsequent turns.
Critical Failure You can't use the item, and you can't try to trick it again until your next daily preparations.

ManipulateYou must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
SkillA general feat with the skill trait improves your skills and their actions or gives you new actions for a skill. A feat with this trait can be selected when a class grants a skill feat or general feat. Archetype feats with the skill trait can be selected in place of a skill feat if you have that archetype's dedication feat.
Assured Identification Feat 2
Source Pathfinder Advanced Player's Guide
Prerequisites expert in Arcana, Nature, Occultism, or Religion
You rarely misidentify an item. When using Arcana, Nature, Occultism, or Religion checks to Identify Magic, if you roll a critical failure, you get a failure instead. If you would misidentify a cursed item because you roll a success but not a critical success, you simply can't identify it instead.

Eye of the Arclords Feat 2
Source Pathfinder Lost Omens: World Guide
Prerequisites expert in Arcana, Arcane Sense
Frequency once per day
Access You are a member of the Arclords of Nex.
You open an incandescent third eye upon your forehead.
The eye can remain open for 1 minute, and you can close it before then with a single action with the concentrate trait. It can remain open for 2 minutes if you're a master in Arcana, or 5 minutes if you're legendary.
While the eye is open, you gain the following benefits:
- you gain the effects of the detect magic arcane innate spell from your Arcane Sense at the start of each of your turns without needing to cast the spell;
- you gain darkvision;
- you gain a +2 status bonus to Perception checks to Seek undetected and hidden creatures and to your Perception DC against Hide and Sneak.
Effect: Eye of the Arclords
After your third eye closes, you are dazzled for an amount of time equal to how long you had it open.
Traits

Magical Shorthand Feat 2
Source Pathfinder Core Rulebook
Prerequisites expert in Arcana, Nature, Occultism, or Religion
Learning spells comes easily to you. If you're an expert in a tradition's associated skill, you take 10 minutes per spell level to learn a spell of that tradition, rather than 1 hour per spell level. If you fail to learn the spell, you can try again after 1 week or after you gain a level, whichever comes first. If you're a master in the tradition's associated skill, learning a spell takes 5 minutes per spell level, and if you're legendary, it takes 1 minute per spell level. You can use downtime to learn and inscribe new spells. This works as if you were using Earn Income with the tradition's associated skill, but instead of gaining money, you choose a spell available to you to learn and gain a discount on learning it, learning it for free if your earned income equals or exceeds its cost.

Unified Theory Feat 15
Source Pathfinder Core Rulebook
Prerequisites legendary in Arcana
You've started to make a meaningful connection about the common underpinnings of the four traditions of magic and magical essences, allowing you to understand them all through an arcane lens. Whenever you use a skill action or a skill feat that requires a Nature, Occultism, or Religion check, depending on the magic tradition, you can use Arcana instead. If you would normally take a penalty or have a higher DC for using Arcana on other magic (such as when using Identify Magic), you no longer do so.
