"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]."
Daruk's Protection is one of the four Champions' Blessings and a Key Item found in Breath of the Wild. It is obtained from Daruk after defeating Fireblight Ganon in the Divine Beast Vah Rudania.
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.
An upgrade is available as a part of the Expansion Pass, in the form of Daruk's Protection +. This upgrade reduces the cooldown to recharge the ability by twelve minutes.
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.
