Static Discharge is a level 2 Conjurations/Air Magic spell which releases charges of electricity at one or more targets adjacent to the caster.

Air Elementalists begin with this spell in their libraries.

Useful Info

Static Discharge deals electric damage to 1d(2 + pow/25) adjacent targets,[1] ignoring AC.

For each target hit directly, an "arc" is created. Arcs will hit a creature adjacent to the previous target, repeating up to 1d(2 + pow/25) times.[2] Each individual arc can only hit a creature once. However, a creature can be hit by multiple different arcs at once. E.g. if there are 2 monsters adjacent to the caster, up to 2 arcs can be created, so each monster can be hit twice.

If an arc hits the caster, its damage is halved. This spell does not affect electricity-immune targets; any arcs aimed at immune creatures will immediately ground out.

The Arc Blade uses a particularly high-powered version of this spell for its special effect.


Static Discharge is a decent attacking spell for its level. It's most helpful against crowds of monsters, as such crowds allow for multiple arcs to bounce through them. Because it ignores AC and EV, it's also good against monsters with high defenses, such as orc warriors and killer bees.

Exercise caution against crowds, though -- much like axes, having more targets for Static Discharge means you'll also be taking more attacks. Unlike axes, Static Discharge can also hit monsters behind the target. When used in a hallway, you can hit 2 monsters while only being hit back by one (but for less damage than if both were adjacent to you).
