Built from blood-soaked wood, the sin pyre looms over the guilty and innocent alike. Save, the construct has been instructed there are no innocents. Set loose in a region, its duty is to seek out secret sins wherever they may lie and burn them away until it burns out quite literally as well. Those wide to its nature do their best to avoid the sin pyre's path and also ensure it never gets set aflame. Alas, it's so very flammable. Cast in a vaguely humanoid shape to start, the construct's frame twists and rearranges as it moves to best navigate its terrain. Sometimes it has extra long legs, sometimes it has four, or eight, whatever is best to keep hunting the sinners that must burn.

Cast the First Stone.

The sin pyre targets a creature with an intelligence of 4 or greater that it can see within 30ft and begins siphoning off their sin. The creature must succeed on a DC 15 Wisdom save or be linked to the sin pyre for the next minute. While linked, the sin pyre gains resistance to all damage except fire and radiant. The other half of the damage that would be dealt from resisted attacks is dealt to the linked creature instead as long as it is within 30ft. The sin pyre also knows the direction and distance of the linked creature in relation to it.
