Burning Hands Statue (4e Trap)
From D&D Wiki
A magical object taking up one square from which a fierce burst of flame can erupt to scorch those nearby. It is typically shaped in the likeness of its creator – a wizard with fingers outstretched – or a fire-breathing creature like a dragon.
A burning hands statue is not triggered until it can hit at least two creatures. It is often used in dungeons or fortresses to control vermin or to ward off invading soldiers, but offers no defense against lone intruders. Canny dungeon architects will place these statues in wall alcoves so that they cannot be approached by two invaders from opposite directions.
