Overview and Core Concept
The PoE Arc Trapper build centers on using a bow or wand to apply persistent arc ailments while you trap enemies around the edge of engagement. The design leverages phasing, curse immunity, and precise trap placement to safely control packs and delete targets. This evergreen guide explains the key mechanics, skill choices, and setup steps so you can adapt the build to current league mechanics and content without chasing short-lived spikes.

Traps provide area control and steady damage, while bow or wand gives you safe application from distance. Phasing and curse immunity reduce downtime, letting you maintain pressure through map content and endgame bosses. Understanding these interactions keeps your setup robust across league updates.
