Demon Statues (悪魔の石像, Akuma no Sekizō)? are a mechanic in Shin Megami Tensei V.
Various demon-like statues are scattered around Da'at. They are remnants of the war that took place a decade ago, and are described as "petrified demons."
Demon Statues, upon interacting with them, grant the option to have their "magic absorbed," which transform the petrified demon into Magatsuhi. This causes every single demon the player has in their roster and party to gain enough experience to level up immediately; the protagonist is exempt from their effects.
