From D&D Wiki
Large elemental, neutral good
Damage Resistances acid, lightning, thunder; bludgeoning, piercing, and slashing from nonmagical weapons
Elemental Form. The elemental can move through a space as narrow as 1 inch without squeezing. It can enter a hostile creature's space and stop there.
Pacifist Breath. The elemental exhales a white cloud in a 90-foot cone. Each creature in that area must make a DC 15 Wisdom saving throw, taking no damage but becoming "pacified" (cannot conduct combat) for the next 5 turns, or taking 9 (1d8 + 5) bludgeoning damage on a successful one.
Everyone sees this elemental differently. It may be a lovely woman, it may be a bulky man. It make be a pink cloud, it may be a statue of gold. These are the rarest of the 7 elemental spirits, only found in the places of greatest happiness. They are more common in areas around the Tower of Vico. Legend has it that when the first man died, his spirit was carried by a light elemental to the afterlife. This man lived a generally neutral life, working hard to get food for him. When he was carried to the afterlife, he was destined to become an elemental; being the first man to have died. His soul split in two, creating the first darkness elemental and the first love elemental. He has become the one who has brought evil to this world, as well as good.
