Cystal is a Pre-Hardmode enemy that spawns in the Corruption biome. It spawns with four shields that orbits around itself while flying towards the player. Upon contact, it will stop in place and inflict the player with the Crystallization debuff which causes them to rapidly lose life and have their movement speed reduced for the duration of the debuff.
- While under the effect of the debuff, a dark grey filter will be applied to the screen which also reduces the player's visibility.
- 1.4.2: Introduced.
