An arc of lightning reaches from the caster to a targeted enemy and chains to other enemies, but not immediately back. Each time the arc chains, it will also chain a secondary arc to another enemy that the main arc has not already hit, which cannot chain further.
Chains between enemies, cheap and consistent.
Level requirement: 12.
