Corruption Altar

The Altar of Corruption is a Pre-Hardmode Corruption-exclusive enemy. Once it spots the player it will start shooting quick corrupted shots at them, which deal 25/ 50 damage and inflict the darkness debuff for 2 seconds. The projectiles also create purple light while travelling.

Upon death it may drop a Corruption Amethyst at a 50% chance.

It has a crimson variant, suprisingly called the Altar of Crimson.

Prior to v1.1, it had tesla turret ai and hence shot projectiles which could one-shot most pre-hm players.
