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. It can even deflect the colossal brimstone laser fired by The Beast.
White beams, such as those used by Dogma in its second phase, are reflected into holy beams similar to those fired by Revelation.
The shield lasts 1 second, and has a cooldown of 3 seconds.
This item belongs to the Seraphim set. Collecting three items from this set will transform Isaac into an angel.
If any charged item is obtained along with Divine Intervention e.g. Brimstone or Revelation, a different fire key may be pressed to put out the shield without forfeiting the charge of said item.
