"A protective power containing the perfect defense of the Champion Daruk. It will automatically protect you from all manner of attacks as long as you're holding [ZL]."
This ability will protect Link from an attack whilst he is holding up his shield. Up to three uses of Daruk's Protection can be held at one time. It can be disabled within the inventory if the player desires.
Obtainment of the blessing requires the activation of the Main Control Unit of the Divine Beast. As such, leaving the Divine Beast without activation will not grant Link the blessing.
Another lesser benefit of the blessing is that it can be used as an emergency source of light inside the darkness veil of the Thyphlo Ruins.
