Crystal Elemental

Crystal Elementals are enemies that appear in Echocave. They are stationary and have a relatively large health pool. They behave almost identically to Gear Elementals; however, unlike Gear Elementals, they can turn to face the player. Charge shots will also reflect the crystal back to the elemental.

Behavior
When approached by the player, Crystal Elementals will begin to throw explosive crystal boulders in an arc towards the player's exact position. They will continue to do this either upon death or until the player leaves.

Beta Crystal Elementals look almost the same as their Alpha counterparts, but have what appears to be two extra cannons mounted on the shoulders. They fire two extra crystal boulders alongside the normal one, aimed beside the player. They also have a slightly faster fire rate and a larger health pool (120 HP). [possibly outdated - beta crystal elemental behavior has changed in 0.23 and needs testing]
