Allowing the Steel Inquisitor to see auras and feel the world around them in a way that is described by the Inquisitors as nothing short of holy and the way the world was meant to be seen.

If a spike is forcibly removed from a Steel Inquisitor's skull all senses are halved and the Inquisitor falls unconscious for 2d6 hours. 

If both spikes are removed the host immediately drops to 0 hit points and receives 2 failed death saving throws as they are put to the brink of death.
