The Syrrus is a saurian monster that inhabits subterranean lakes. It remains mostly submerged when attacking, so its size and shape are open to speculation, but what does emerge is not very reassuring. The creature has a long and very strong neck many times the size of a human, scaled in brilliant blue-green hues. Its head is draconic, with an elongated mouth, scaled plumage, and horns.
The Syrrus attacks exclusively with its breath, which appears to be a cone of super-chilled caustic mist. It deals high damage-over-time in a large area in front of the attack trajectory.
