Angry Nimbus

The Angry Nimbus is a rare Hardmode enemy that spawns when the weather is rainy on forest biomes. It will follow players around the map, attempting to kill them with a rain type attack similar to that of the Crimson Rod and the Nimbus Rod. It floats above player making it almost impossible to hit with close-range weapons. They are immune to the Poisoned and Venom debuffs

Trivia
•Nimbus clouds are common clouds that are usually dark in appearance due to their dense water content.

•Cumulonimbus clouds resemble the angry nimbus more closely, yet are not nimbus clouds. They are precipitating Nimbus clouds whose name roots from the latin terms cumulus ("heap"), and Nimbus ("rain, storm-cloud"), which explains Angry Nimbus' lumpy appearance.
