Day

Day is a stronger version of the Light spell. Casting it creates a bight light sphere, which illuminates a greater area and therefore is more useful than the lesser spell.

Trivia

 * The spell is bugged as the sphere fizzles out after some moments, but still drains mana as if still on. It has to be dismissed to stop the drain.
 * This spell uses the same Words of Power as the Great Light spell from previous games. However, Great Light creates a lightsource of equal strength than Light, but making it last longer, while Day creates a strongest source of light.
