UI对察觉/隐匿的补充解释将aware分为了 Unaware/Aware of Presence/Aware of Location/Observing 四个等级
而在 Unware 的详述里直接点名了惊愕现身，据此可以认为惊愕现身是个对PC战斗约等于不存在的能力。
Unaware: On one end of the spectrum, a sneaking creature can succeed at Stealth well enough that the other creature isn’t even aware that the creature is present. This state allows the sneaking creature to use abilities such as the vigilante’s startling appearance. The Stealth skill description in the Core Rulebook says that perceiving creatures that fail to beat a sneaking character’s Stealth check result are not aware of the sneaking character, but that is different from being totally unaware. This is also true of a creature that has previously been made aware of the creature’s presence or location (see below) but is currently unable to observe the sneaking creature. In those cases, the sneaking creature can’t use abilities such as startling presence.
诺戈巴那条其实没啥说服力，毕竟惊愕现身本身也是这么写的，应该是说的事前保持隐匿的例子而不是所有使用类似手段都算。
Whenever a vigilante with this ability attempts an attack against a foe that is completely unaware of the vigilante’s presence (usually due to Stealth or invisibility)
