Double tapping a fire key will create a Divine Shield that slowly moves in the chosen direction.
The Divine Shield has a variety of effects.
Enemies are pushed back in the opposite direction, completely reversing their trajectory with some added momentum. If they hit a wall or obstacle while being pushed, they take 10 damage and deal 10 damage to enemies they hit.
Enemy tears are reflected, dealing damage back to enemies depending on the source of the tear.
Enemy Brimstone lasers are reflected, dealing 7 damage per tick (105 damage per second) to enemies hit by the reflection.
The shield lasts 1 second, and has a cooldown of 3 seconds.
