When the wizard casts Chain Lightning, arcs of electrical energy burst from his fingertips. These brilliant arcs of lightning leap at all enemies near the target creature, burning them with electrical damage. The lightning causes 1d8 points of electricity damage for every level of the caster to the target creature, 1D4 points of electricity damage to all creatures within 10 feet of the target creature, 1D2 points of electricity damage to all creatures within 20 feet of the target selected, and 1 point of electricity damage to all within a 40 feet of the target. If the target of the lightning saves against spells only half damage is inflicted. If a creature falls into the outside radius of this spell, a saving throw negates all the damage except one point of electricity damage, which is enough to disrupt spell-casting. Although allied creatures aren't directly affected by this spell, they will still suffer a minor burn ~ 1 point of electricity damage per level of the caster (a saving throw doesn't apply in this case).
