Hello everyone! Welcome to Cassie's Arc Unleash Inquisitor guide. This guide will cover the fundamental concepts, as well as some advice for new players trying it as their first build.

This build was inspired by my personal desire to see a self-caster succeed in downing endgame bosses, as well as a general dislike of trigger setups for spells. Initially, it wasn't looking very promising, but then I stumbled onto dual Shimmeron tripling my POB. It was all uphill from there, with several additional discoveries along the way. While I did largely develop and play this build in Scourge league, I believe it got the exact power boost it needed to be a good option from 3.17 changes.


- Great for leveling, and especially your first time to reach maps, with many core uniques keeping it simple.
- Unleash seals and no spell echo, giving very high mobility for a self-caster.
- Very good map clear.
- Extremely tanky.
- Able to down all boss content.


- Almost unplayable for SSF and hardcore due to the dependence on uniques.
- Relatively expensive to finish. If your intent is to kill all the major bosses, you'll need a lot of investment. However, you can reasonably complete content on about 5-10ex budget.

1. How to use Path of Building
Path of Building Community is an incredibly important tool for managing character builds in Path of Exile. In fact, you won't be able to view this guide in full without it. You can find the download here: https://github.com/PathOfBuildingCommunity/PathOfBuilding/releases

After installing POB Community, you will need to import my build to view it. Open the program, and create a new build. Then, click on the Import/Export build button in the top left. From this page, copy the POB link, which is a pastebin, poe ninja, or pobbin URL. Do not open the link, only copy the link to your clipboard. Then, back on POB, click on "Import from website", paste the link, click import, then click import again. You will now have my build imported.

On the bottom middle of the screen, you will see a dropdown menu with "98 (finished)" selected; click this menu to view lower level passive trees. You should work through these in order as you level up.

Click the "Items" tab on the top, there you can see an overview of the final items used in the build. In the top middle of the screen, you will see a dropdown menu that says "Final Setup", you can click this menu to view the alternate gear sets used, including leveling and budget item setups. You will need these.

Then, click the "skills" tab in the top left; this will give you an overview of the skill setups used in the guide. Not all of the gem sets are used, pay attention to the title of them. You only need one Arc setup. MAKE ABSOLUTELY SURE YOU GET A JAWS OF AGONY WEAPON SWAP SETUP FOR MAPPING.

2. General Advice for New Players
Having a loot filter installed is extremely important to playing efficiently. There are many guides available for how to install these, but in short, you copy them into documents/my games/path of exile. I recommend Neversink's Strict filter to start, eventually moving up to Uber Strict later on. You can find Neversink's loot filter here: https://github.com/NeverSinkDev/NeverSink-Filter/releases

Many newer players get confused by skill gem links. This is explained in the very beginning of the game, but I'll explain it in brief here. Essentially, there are two types of skill gems: Active, and Support. Active gems create a skill you can use by pressing a button on your action bar. Support gems are used to 'support' these active skills. In order to gain the power of a support gem on a skill, you must have it linked with that skill, inside your armor. For this, you need an item to put the two desire skill gems into, with a "link" showing between the sockets they fit in. You'll know it when you see it. If you've done this correctly, then the ability on your action bar will have a tiny letter icon over the larger icon, indicating which support skills are working.

Midgame can be quite tough when you don't know what you're doing. One of the big secrets is to use "Seething" or "Effusive" life flasks. Starting around level 40/act 4, you can grab a sacred or hallowed life flask from the vendor, then use transmutation orbs/alteration orbs/augmentation orbs to make a life flask with these mods. On pressing this button, you will instantly heal to almost full health. You can also use it rapidly.

Finally, learning to be efficient early can go a long way to preventing burnout. Many new players spend a lot of time clearing out Campaign areas, but you really don't need to do this. Focus on finding the quest item or exit you're looking for, then leave. You can always spawn new campaign areas full of monsters by Control-clicking either the waypoint node in the waypoint menu to open a new instance, or control-clicking the door. You don't need all the monsters dead.

3. Scaling
This section will break down each piece of scaling involved in the build. It won't be completely comprehensive, but should provide an understanding of the mechanics.

Primarily, this build scales with power charges. By using Inquisitor with Inevitable Judgement, we're able to deal full damage to bosses without curses or exposure to shread their resistance. To this end, 100% crit is achieved primarily by scaling Power Charges with maximum power charges, and one to two Shimmeron wands. Shimmeron provides 10% crit multi and 0.3% base crit per power charge, among other stats. With nine power charges and two shimmerons, this adds up to 180% crit multi and 5.4% base crit. Power charges already provide huge critical strike bonuses, but this makes it so we hardly need crit from any other sources. Alternatively, an Aegis Aurora POB is included, which I prefer to use for more consistent bossing.

Power charges are not just for crits, however. We also get a huge bonus to mana regeneration and damage from the Disciple of the Forbidden wheel. Shimmeron provides a flat lightning damage bonus to spells as well. By getting the Inner Conviction keystone from Militant Faith timeless jewel, we get 3% more damage per power charge for 27%, while disabling frenzy charges. In our main six-link setup, we use Power Charge on Crit Support, which grants 4% more damage per power charge, adding up to 36% and keeping our power charges up consistantly. Void battery was considered, but using Void Battery costs a huge number of passive tree points to offset the missing crit from the second Shimmeron.

While not a popular option, Shock effectiveness provides another gigantic multiplier to our boss DPS. In ordinary circumstances, you'll only be shocking a pinnacle boss for about 20%, but by taking these minimal nodes, we can raise it to 40-50%.

Another unusual, but super powerful element of this setup is the use of Unleash. Because Spell Echo is unreliable due to locking you in place while casting, leading to many frustrating deaths, this build uses Unleash and cast speed instead. The biggest benefit of Unleash is clear speed, because you can cover six times as many targets in one cast with all five seals unleashing. However, this is also extremely useful for bosses, as it effectively gives a 300% more multiplier on your first hit after moving around to dodge boss mechanics. Mobility is the name of the game.

By no means a controversial choice, this build also uses a large amount of energy shield, protected from chaos damage by Shavronne's Wrappings, with Pain Attunement and extra auras for extra damage.

Through either Determination or Radiant Faith depending on your budget, the build has anywhere from 10-20k armour, depending on flask uptime. This makes it very stable against many small hits in maps.

Shimmeron causes a significant amount of lightning degen. To offset this, the build uses a combination of energy shield regeneration, and very high energy shield leech with Ghost Reaver. Energy leech is very nice for sustaining, which is ordinarily a problem for some caster builds.

4. My Personal Gear (Expensive and not required)

5. Gems
For the main six-link setup, we use Anomalous Vaal Arc, linked with Unleash (mandatory), Power Charge on Crit (mandatory), Added Lightning Damage, Increased Critical Damage, and Faster Casting.

If you're low on mana, you can use Spell Echo instead of Faster Casting for half mana cost. We don't use Spell Echo in our main setup because it locks you in place and kills you, despite the slightly higher DPS. It's a little worse than usual with an Unleash setup, because the 10% damage reduction applies to Unleash charges too.

If your crit with full power charges is under 70%, you can use Increased Critical Strikes instead of Added Lightning.

For the main aura setup, which I recommend placing in your boots, you will use Determination, Discipline, and Purity of Elements with enlighten 3. Once you have the super expensive Forbidden Flame and Flesh pair, you would use Enlighten 4. You can use "Discipline has 25% increased mana efficiency" mastery instead of enlighten 3, temporarily for budget.

Your life auras, used to activate Pain Attunement ONLY after getting Shavronne's wrappings, will use Zealotry, Clarity, Arrogance support, and Enlighten 3. All that Enlighten does is let you use a higher level Clarity, it's not necessarily required. This setup should reserve as much of your life as possible.

In your helmet (which has strength alignment), you'll use Cast When Damage Taken, Enfeeble, and Molten Shell, with Increased Duration support. This is just a basic automatic defensive setup.

On one wand, we use Orb of Storms, with Power Charge on Crit and Increased Area supports.

On the other, we use Flame Dash with Arcane Surge 6 and Faster Casting.

In our weapon swap, we use Jaws of Agony to throw Fire Trap with Multiple Traps and Cluster Traps, to generate power charges out of combat. THIS IS VERY IMPORTANT.

6. Pantheons and Bandits
For the primary Pantheon, we use Arakaali to offset our own Shimmeron degeneration effect. You can also use Solaris for very lategame boss fighting, particularly if you use the Aegis Aurora variant, or end up with Mageblood.

For the minor god, Ralakesh is very nice for preventing bleed deaths when your bleed immunity flask is down. Tukohama is another good option, if you have Mageblood taking care of that.

For bandits, help Alira. Once you know what you're doing in very very lategame, you can switch it if you want to.

7. Map Mods
- No regeneration
- Elemental reflect

- Cannot leech from monsters
- Reduced recovery rate

- Reduced aura effect
- Extra projectiles
- Lower max resistances
- Monsters steal charges on hit

Free loot:
- Shocked, ignited, or chilled ground

8. Recommended Atlas Tree (optional)

This atlas tree focuses on Blights, and in particular Blight-Ravaged maps, with a side of Incursion, Ritual, and Eater.

If you don't know how to farm Blight-Ravaged maps with just ring enchants and no damage, I highly recommend watching Tripolar Bear's tutorial: https://www.youtube.com/watch?v=VBwXf3MzvXM

For ring enchants, use "Your Meteor Towers create Burning Ground for 3 seconds on Hit" (indigo+violet) and "Your Chilling Towers freeze enemies for 0.2 seconds while they are affected by chilling beams". In particular, watch out for the stun immune map mod and the movement speed cannot be reduced mod, when you're rolling the blight maps. Don't corrupt them.

Once you finish your questlines and atlas completion (perhaps challenge grinding), you'll use Eater of Worlds influence on your map device, with the good passives. This is primarily for pack size and drops from shrines, especially when things like "Eldritch minions have a 2% chance to drop a scarab" come up. Because we have Purity of Elements, a lot of the drawbacks on shrines like shocking ground, sap on hit, etc, do not apply to this build.

We pick up every Ritual node in this tree as well, which you will use to occasionally hunt for big drops. It's fairly common to get 10c or even an exalt from Rituals, but not usually worth investing sextants or map device crafts into.

Alva nodes are also used, to run Alva for temples with double corruption item/gem rooms and sacrifice altars. You can pretty consistently make 1-2ex temple chronicles with this.

For favored maps, you block bad ones using the Shadow Shaping notable. Singular focus converts non-favored blight map drops into currency which is bad. Blight maps also have a tendency to not drop as your favored maps very often, so we use Shadow Shaping to make the interspersed regular maps we run more profitable, rather than focusing on one.

For fragments, you'll use blight, legion, and elder or shaper scarabs. Legion is blocked for a 2% boost to other mechanics at no penalty, since scarabs force it to spawn. It's unknown if blight block disables mycelial swarm, so it's left alone. If it turns out blocking disables scarabs, then remove some of the blocks for your scarabs.

Nice build, what do you think about using the new "Melding of Flesh" jewel to make u 90% all res and possible Defience banner?

I've added a setup that includes melding and max res clusters, definitely worth having the option, but level 98 is necessary to fit all the resistance and jewel sockets. Probably a more cost-efficient option than buying Sanctuary of Thought forbidden jewels, actually!

Defiance banner doesn't quite fit the mana reservation in lategame. The build already struggles a bit on reservation and mana sustain.
