Ghostly Swoop [>] The sluagh reaper becomes incorporeal until the start of their next turn, and Flies up to their fly Speed. While incorporeal, they are immune to precision damage, and have resistance 10 to all damage (except force, ghost touch, or positive); this resistance is doubled against non-magical damage. After using Ghostly Swoop, the sluagh reaper can't use it again for 1d4 rounds.

Sneak Attack The sluagh reaper deals an additional 3d6 precision damage to flat-footed creatures.

Steal Soul[two-actions] (necromancy, occult) The sluagh reaper touches a dying creature or a creature that died within the past 1 hour. If the target is a dying creature, it must attempt a DC 28 Fortitude save—on a failure, its dying value increases by 1 (2 on a critical failure). If the target is dead, it receives no save and the sluagh imprisons its soul in a small, grimy sack that keeps stolen souls fresh. The sack is magically locked. Any sluagh can open it without difficulty, but any others must Pick the Lock (DC 35) or use dispel magic (5th level; counteract DC 32). A creature can Interact to empty an unlocked sack, which frees the souls but doesn't return them to life. While a soul is imprisoned, it can't be brought back to life by any means short of a wish or miracle. The sack can hold 12 souls at a time. Sluagh reapers typically attempt to return the souls to a queen so she can devour them.
