Polarities Mod/Uraraneid

Uraraenids are a Hardmode crimson-based enemy that appear during. They move by jumping towards the player, choosing between a series of three small jumps or one large leap. To attack, they shoot sprays of ichor upwards that are aimed to fall onto the player's position, either firing a series of single projectiles that cover a sweeping area around their target or launching a large cluster of several shots at once. After each action, they will randomly pick one of the three that they did not perform last to use next.

Trivia

 * They are named after Uraraneida, an extinct order of ancient arachnids; the name also brings to mind "urea", referencing the occasionally urine-like depiction of ichor in Terraria.
