Chain Lightning
Gives a 25% chance on attack to release a Chain Lightning that hits eight units, dealing 160 magical damage to each, 500 bounce range. Mjollnir is a Unique Attack Modifier that stacks with other Unique Attack Modifiers, but overrides them when Chain Lightning occurs.

Static Charge
Places a charged shield on a target unit, when that unit is damaged, there is a 20% chance that lightning will strike the source of the damage and 2 nearby enemies. Lightning deals 200 magical damage, the damage source and secondary targets cannot be more than 900 range away, the 3 targets hit must be in a cone with a 125 starting radius, 475 distance and a 300 final radius. Cannot trigger more than once per second and will have no effect if cast on a unit that already has a Static Charge active on it. Double clicking on the item will cast Static Charge on yourself.
