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

Useful Info

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

For each target hit, an "arc" is created. Arcs will hit a creature adjacent to the previous target, repeating up to 1d(2 + pow/25) times. 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.

Strategy

Static Discharge is most helpful against crowds of monsters, as such crowds allow for multiple arcs to bounce through them. The ability to bypass AC and EV lets it see use against single monsters with high defenses, like orc warriors or killer bees. It's also just a good (level 2) attacking spell.

Exercise caution when using this spell against crowds, however -- much like axes, having more targets means you'll also be taking more attacks. But unlike axes, Static Discharge can hit monsters behind the target. When used in a hallway, you can hit 2 monsters while only being hit back by one.

History

• Prior to 0.31, Static Discharge arcs dealt 1d(2 + pow/15) to the player, even if a monster was casting the spell
• Prior to 0.30, Static Discharge dealt 2 + 1d(3 + pow/8) damage, hit up to 1d(2 + pow/20) targets, and had a power cap of 100. rElec monsters were fully immune to this spell.
• Prior to 0.29, this spell dealt 2 + 1d(5 + Power/10 + (1d(Power)-1)/10) damage. The number of targets an arc could hit wasn't predetermined before cast; the power was reduced for each arc of the spell, and power determined the chance of making a new arc.
• Prior to 0.27, this spell was a level 3 spell.
• Prior to 0.26, insubstantial wisps could cast this spell.
• Prior to 0.13, this spell would deal less damage to levitating or flying targets.
