The Scripture of Light is a passive item, taking on the appearence of a scroll.
Scott Rhodes starts with this item.
It gives the holder additional oppurtunity, as on the third level of every area, a pillar of light is hidden somewhere on the stage. Entering the light will consume it, and give a blessing to the player.
The blessing is picked randomly, being a 50% health refill, a pile of loot at their location, or a small but permanent stat increase.
