Arc
An arc of lightning reaches from the caster to a targeted enemy and chains to other enemies, but not immediately back. Each time the arc chains, it will also chain a secondary arc to another enemy that the main arc has not already hit, which cannot chain further.
How to get Arc
PoExplorer currently classifies this as skill gem. That label comes from the reviewed source record; where the source does not provide a dependable location or recipe, PoExplorer does not invent one.
How to use Arc
Chaining supports clearing naturally; mana, cast usability, and focused damage still need their own answers.
Supports that fit this skill
Eligible means the support's allowed and excluded game-data types passed PoExplorer's conservative compatibility check. Recommended appears only when the source explicitly recommends it.
