Arcjolt is a level 5 Air Magic/Conjurations spell which hits monsters within 2 tiles of the caster, as well as anything adjacent to a previous target.

Useful Info

Hits all monsters within 2 tiles of the caster, or adjacent to a monster previously hurt from this spell, up to your line of sight. This spell deals full damage regardless of how far a target is or how many targets are hit. As a spell dealing BEAM_ELEC damage, it also ignores half of any target's AC.

Monsters who are immune to electricity are not considered targets, and do not extend the spell's area. Allies protected from harm (such as the Hepliaklqana ancestor or plants under Fedhas) are also not targets.

Strategy

Arcjolt can hit huge packs of clumped enemies. Remember that you'll be close to said enemies; don't get too greedy with your arcs. Helpful against packs of enemies, such as yaks and spiders.

History

• Prior to 0.31, Arcjolt only hit targets that were 1 tile away from the caster or another target. However, allies protected from harm counted as targets.
• Arcjolt was added in 0.30.
• During its initial implementation, Arcjolt would conduct through metal walls with infinite range. In levels with metal walls, you could use Arcjolt to hit things from the other side of the floor.
