'''Chain Lightning''' is a level 8 [[Conjuration]]-[[Air Magic]] spell that arcs from target to target (including leaving your sight, going around corners, etc) until it grounds out. You do not aim it. Due to its nature, be prepared for it to hit you and your allies, possibly repeatedly. The arcs, including the initial casting, work most reliably on shorter distances.

Even without resistance and with many arcs, you'll likely never take more than 20 damage.

This spell releases a massive electrical discharge that arcs from target to target until it grounds out.

Chain Lightning is a devastating but unpredictable level 8 Conjurations/Air Magic spell which unleashes a massive surge of electricity, leaping from target to target with perfect accuracy and devastating everything in its path. There is no way to actually aim the spell - when cast, the surge simply comes into being, blasting the nearest target and wreaking havoc among nearby units until its power is spent and it grounds out. Any unit, including you and your allies, is treated as a valid target, and the spell is capable of zipping around corners or going beyond your line of sight, but where the spell goes exactly is determined by the RNG.

Increasing your spellpower improves both damage dealt per jump and number of jumps before grounding out. Although you'll usually be injured by this spell, it deals significantly reduced damage to you, particularly if you happen to have rElec. Even without resistance, taking more than 20 damage in a single casting is unlikely.

Mechanics

The damage on each discharge is 5d(5+Power_left*2/15). On the first discharge, Power_left simply equals the spellpower for this spell. After each discharge, this amount is decreased by 7+1d13. When Power_left reaches 0, the spell grounds out. If the discharge hits a target beyond your line of sight, Power_left is halved after subtracting the standard 7+1d13.

Strategy

As an area-of-effect spell for taking out multiple small threats, Chain Lightning works well enough, hitting multiple nearby targets for decent damage regardless of how they're spaced. Its real strength, however, lies in casting it against a single nearby foe; the surge will leap back and forth between you and your opponent for massive damage. At moderate spell power, Chain Lightning can take out powerful uniques in 2-3 castings. At maxed out spell power, it becomes one of the most potent damage sources in the game (so long as the target isn't electricity resistant). Wielding a staff of air provides a significant boost to both damage per jump and number of jumps, and grants you resistance to the self-damage; definitely consider wielding one if you can find it.

Remember that plants, fungus, and bushes are all valid targets for Chain Lightning, and that they'll take their share of the damage, reducing the spell's effectiveness. When possible, lure targets away from any such harmless targets.

Followers of Beogh, Yredelemnul, or any other character that makes heavy use of allies should use extreme caution before casting Chain Lightning. You are almost guaranteed to injure or kill your allies in the process.

Chain Lightning was added in 0.1, replacing Orb of Electrocution.
