Entity: Plunderer of the Hive's Riches

Source Pathfinder #217: Death Sails a Wine-Dark Sea pg. 78

You take what’s yours, even if an army should stand in your way. You gain the Energized Spark feat, with your choice of either poison or sonic damage. When you critically succeed at a Strike, the taste of honey fills your mouth as you plunder part of your foe’s vitality for yourself, gaining temporary Hit Points equal to half the creature’s level that last for 1 minute.

When you Spark Transcendence, a mass of buzzing insects fill the air around you, granting you concealment until the beginning of your next turn. You can’t use this concealment to Hide or Sneak, as normal for concealment when your position is still obvious.
