Gabriel

Gabriel is one of the possible Wormhole guardians.

Swift Death
Makes Gabriel fly horizontally and vertically twice in succession, leaving a trail of blood behind that damage the player.

Total Annihilation
When Gabriel lose 50% HP, he stops using Swift Death and starts to spawn an ice block that the player needs to stand behind and line of sight Gabriel or else he will one shot you. Don't stand super close behind the ice block because after total annihilation is over, the ice block explodes into many small ice blocks that shoot out in a circle pattern from the ice block and will heavily damage you.
