Sroller

The Sroller is a Hardmode, post-Golem enemy summoned by the Solar Pillar during the Lunar Events. It can curl into a ball and rolls at the player, potentially dealing a large amount of damage on contact. Although they appear to have a visual height of 4 tiles, they can pass through 3 tile-tall spaces.

Trivia
