Spell of flash: upon casting it, you are prompted to choose a direction in which to hurl a “ball of light” object.

• The ball belongs to the venom class because it is insubstantial; it does not ordinarily deal any damage.
• It possibly has no maximum range and can fly across the entire map if there’s a clear path.
• Upon hitting something, it bursts and permanently lights up a 3x3 area. If it hits a monster, the monster is blinded. If the monster is a gremlin, it takes extra damage from the flash.

It’s not clear which spell school this should be in:

• Divination, because it is similar to the spell of light?
• Attack, because it can be used as an attack?
• Enchantment, because it debuffs stuff?
• Clerical, because light-based attacks fit the flavor?
