In this guide, we’re diving into one of the strongest caster builds in Path of Exile 2: the Arc Stormwaver. This build, shared by Goblin Inc. on his YouTube channel, has explosive clear speed, high bossing DPS, and a smooth power curve once you get past a rough mid-game. Now, let’s dive in.

 

Core Mechanics

Arc and Lightning Infusions

Arc has been slightly reworked. On its own, it chains between enemies and deals solid lightning damage. When infused with lightning, however, Arc chains more times and deals 200% more damage. The entire build revolves around ensuring every Arc is infused. This is achieved through Cast on Elemental Ailment combined with frequent shock application. Every time you shock enemies, you enable more Infusion uptime.

Snap and Infusion Storage

The skill Snap consumes shocks in a large AoE and spawns Lightning Infusions. By taking the Shocking Limit node, you can hold up to 4 Lightning Infusions at once, letting you stockpile buffs and carry them into the next pack or boss.

Unleash Support

Unleash makes Arc fire extra echoes. Each echo consumes Lightning Infusions, massively increasing AoE clear and burst damage. It feels fantastic while mapping, since every cast effectively becomes three.

Ascendancy – Storm’s Recollection

This ascendancy power respawns Lightning Remnants three seconds after pickup. Against bosses, this means every single Arc cast is infused, giving you unmatched consistency and damage output.

Shock Scaling and Damage Rotation

Arc also has a unique modifier: it increases the magnitude of shocks inflicted by 50%. Combined with Strike Twice, which allows you to apply two shocks simultaneously, you can stack devastating debuffs on bosses.

The synergy is so strong that you don’t even need to finish your intended rotation, as bosses die before the full cycle completes.

Key Supporting Skills

Orb of Storms: Generates Lightning Infusions when it expires. With Overabundance (extra Orb) and Compressed Duration, you can set up multiple Infusions before fights. Ascendancy makes them respawn, further multiplying the generation. And if you ever need to get Orb of Storms quickly, you can buy it safely and conveniently from MmoGah — fast delivery and secure service make your build progression much smoother.

Mana Tempest: A huge damage amplifier. Doubles damage and increases AoE for Arc and Lightning Conduit. Always activate it before casting your main skills.

Shaper of Winter + Heavy Snows (Optional): Converts all damage into chill magnitude. This slows enemy movement, attacks, and casts by up to 50%, giving a powerful defensive layer — especially useful in Abyss and against tough elites.

Passive Tree Progression

The Sorcerer tree has seen major changes. Here’s what to prioritize:

Defensive Transition

A reminder: damage is defense for this build. Faster kills mean fewer chances to die. Don’t be afraid to prioritize offensive nodes early, then respec into ES once you can handle CI.

Gear Priorities

Since the Arc Stormwaver relies on high Energy Shield and spell scaling, gearing is all about balancing offense, survivability, and utility. Here’s how to prioritize each slot:

Weapon (Wand)

Amulet

Chest / Helmet / Gloves / Boots

Rings

Charms

Final Thoughts

The Arc Stormwaver combines everything players want in a caster build: lightning-fast clears, effortless scaling, and bossing power so high that encounters end before mechanics begin. While it struggles in the late campaign and the first steps into mapping, once you reach CI and start stacking spell levels, the build becomes unstoppable. If you’re looking for a top-tier PoE 2 caster that can handle all content with minimal gear requirements once it’s online, this build is for you.
