An electrical discharge strikes a primary target for 1d3+3 electrical damage per caster level, up to a maximum of 20d3+60 at caster level 20. It then arcs to up to 4 other nearby targets hitting each of them with a similar lightning bolt. A successful Reflex save reduces the damage by half.
Testing on 15.2 confirmed that Chain Lightning is capped at caster level 20. See:
Certain thin terrain obstacles can be penetrated by Chain Lightning, when few other attacks will work.
Note: This spell has a far more limited AOE (roughly the standard AOE area) than other similar level AOE nukes such as Delayed Blast Fireball. That combined with its target limit, can greatly reduce its effectiveness versus very large groups of enemies. However, you can reliably strike most groups of enemies if you use it with Enlarge.
