Cast Light

Cast Light is a sorcery in Dark Souls.

Availability
Dusk of Oolacile sells this spell. She is found in the Darkroot Basin.

Usage
Cast Light makes a ball of light appear above the player's head. It is useful for illumination in the Tomb of the Giants. Outside of this area, there really isn't much point in using Cast Light.

Cast Light is one of only three light sources in the game (along with the helmet Sunlight Maggot and the offhand item Skull Lantern. It can be considered the most useful of the three as it does not require players to sacrifice an item slot and lasts a very long time; however, some players may prefer the Sunlight Maggot if they have insufficient attunement slots or intelligence to use the spell.
