Lion BladeSource Shining Kingdoms pg. 170Taldor’s official teeth in the shadows was founded in 1629 ar by Yanual and Izora, children of the late Goscelyn II and half-siblings to the Bastard Prince Penticus IV. Today, the shadow schools below Oppara, Cassomir, and other settlements teach a strict curriculum involving anatomy, politics, and even hypnotic meditation. This grueling program eliminates recruits until only the best remain. About one in ten students become fully recognized agents. The rest often become part of the supporting network as Lion Kiths, who retain a measure of their skills after leaving. Those who don’t become a Lion Kith leave to return to their bardic studies under vows of secrecy or cut off all ties.
Most agents require about five to ten years of active field service before they’re recognized as senior agents who can become an instructor at a shadow school. It is not unusual for masters of the shadow schools to poach one another’s graduates to exchange techniques and skills.
If you wish to play a PC who’s a Lion Kith, you can limit your feat selections from this archetype to that of level 6 and lower.
Additional Feats
Source Player Core pg. 215 2.0Some archetypes include a list of “Additional Feats” that appear in other sources. The list includes each feat’s level, which might be different than normal when gained from the archetype. You can take the feat as an archetype feat of that level, meaning it counts toward the number of feats required by the archetype’s dedication feat. When selected this way, a feat that normally has a class’s trait (such as the fighter trait) doesn’t have that class trait.

fascinate your target. This works only if you're attempting to fascinate one target. For example, if you were an expert in
Performance, you could choose to target multiple creatures normally or target one creature and fascinate it on a success.

Archetype Source Shining Kingdoms pg. 171Archetype Lion BladePrerequisites Lion Blade DedicationTrigger You succeed at a save against a
detection,
mental, or
scrying effect
You’ve learned how to analyze and fake your responses to the most common magic used against spies. You can attempt to identify the effect via
Identify Magic using the magical tradition skill of the effect or
Espionage Lore, even if you didn’t notice the spell being cast.
If you successfully identify the triggering effect, and it would normally fail or have no effect, you can make the caster of the triggering effect think the effect or spell succeeded. If they would obtain a result, such as receive a piece of information, you decide what that result is. If the effect would influence you to take certain actions, you can make it appear as if you were affected and attempt to play along; if the effect normally establishes a mental link, it functions normally, but you can disregard any commands you receive through the link.
