Spark Inquisitor was my first tanky character ever back in Archnemesis League and I wanted to play again, but I made a twist there. My budget for this can't be over 1 Divine Orb.
Let's see what things we got on the damage side. Spark is a fast moving projectiler that can collide with the terrain because of that our clear highly depends on the projectile speed and the projectile duration. If you have high projectile speed, you can kill enemies off screen and shoutgunning the bosses near the walls because of that the real DPS is hard to calculate.
In the PoB, you will see our DPS multipled by 3 because we can safely tell a projectile can hit the same enemy 3 times before the projectile disappear. The best possible multiplier for a spell build is to go low Life and use Pain Attunement keystone, which is giving more Spell Damage if we are on low Life. We achieve this with a few things. Use Blood Magic keystone via a relic. Don't worry about this. You can get Blood Magic on any relic with Lycia's Invocation and only costing for you 10 Chaos Orbs. But before you use on your favoirte relic, try it out on a bad relic and see if you like the playstyle with this build.
Now, all of our spells and abilities will cost Life and reserve Life instead of Mana. We will use Petrified Blood with this. We can only recover 50% health and the remeaning 50%. We can reserve with auras. Our auras that is reserving Life the following Vitality, Purity of Fire, and Petrified Blood. With all of this, you now only left around 51% health.
Use Eternal Blessing with Determination. You can use the mentiond auras and this even if the gem staets. You can't use other auras because we don't reserve Mana, we reserve Life. So, we have a free aura. This is all good. But how will we deal damage if all of the auras is defensive? This is when our big life pool came in. We have almost 7k health because of that. We will use Rathpith Globe unique shield. This shield gives us Spell Crit and Spell Damage per 100 maximum life. Alone this, shield is 57% of our damage. Beacuse of our really high life regen We can sustain Rightous Fire, which is also granting more Spell Damage.
On the defensive side, use Petrified Blood. When you take a hit, it will be stagger a percantange of the damage and it will be dealt over 4 second to you. You can't recover above 50% health if you use this skill. But it will enable you to overleech, giving you extra life recovery option.
We achieve this with Lightning Damage, Leech implicits on our gloves. Use Determination with Eternal Blessing and Molten Shell as our guard skill and of course Vaal Molten Shell for even more defensive. Convert all of our Evasion Rating to armour with Iron Reflexes keystone. Use Purity of Fire for maximum fire resistance because we use Rightous Fire and it will help to mitigate the degen. Use Vitality for the life regen. Also use a Watcher's Eye with life recovery rate while affected by Vitality.
You only need reverse half of your life if you go over 50%, you will not able to overleech. You can check the number by a simple math, just divide you maximum life by 2 and see if your unreserved life is more than the reserved life. Use Glorious Vanity timeless jewel with Corrupted Soul. We gain our maximum life as extra Energy Shield.
These are few important things you need in the build. Aim on your Wand Lightning Damage to you spells, cast speed, projectile speed, and +1 to all lightning skill gems. On your amulet, life resistance and +1 to all lightning skill gems. Our annoinment is Heartseeker. We use 5 unique item which are not expensive in the build, such as Rathpith Globe, unique shield and they increase huge damage for us.
We use Voidwalker unique boots because Spark needs pierce for the clear and we get Pierce with this boots. We use Mark Of The Shaper unique ring. It gives HP and Energy Sheild and Spell Damage, but you need an Elder Ring on other slot to get the Spell Damage bonus. The magnate unique belt is a really good item for the price and it gives a tons of damage and resistance, but you have to get 400 Strenghth for it, which is really easy with the tree we use. We use Skin Of The Lords, which is a unique body armour. There is multiple keystone you can get on this piece of gear. It's not really important what keystone you get because there is a couple that you can't use because it will ruin the build.
In the PoB, you will see 3 different gem link setup. Use accordingly because I don't know what socket colours you will get. You can't modify the socket colours on this item. Use the link setup that is in the PoB because this 3 is the great links you can use with this skill. Also the reason why I give you many options is because the price range with the right socket colour can be higher than your budget in my perspective 1 divine range. You can craft the following implitics with the Eldrich Currency.
I just used the lesser ones. They are not expensive, like 1 Chaos Orbs for 8 lesser one. So, you could easliy get the following rolls. On your gloves: Lightning Damage leeched as life and have chance to unnerve enemies. On your helmet: Spell Damage and Lightning damata to spells also worth to mention. We use Sparks, fires, addtional projectiles. I'm using a cheaper one because there is two version of this. You can get 2 additional projectiles or you can get the 3 a additional projectiles. It's up to your budget.
Pantheons that we use is the following:
On your Major: Soul of the Brine King is important to uprgade. Avoid to being frozen and reduced effect of chill.
On you Minior: Soul of Garukhan, which reduces the Shock Effect on you.
I just want to highlight a few things on the Passive Tree that you need for the build. Use a Watcher's Eye with incresed life recovery rate while affected by Vitality and Blue Nightmare unique jewel. On this spot, you really need this. It will give us Power Charges while mapping. Use Gloiurs Vanity timeless uniqeu jewel with this line sacreficed in the name of Doryani and take Corrupted Soul keystone.
The rest of the jewel are rare with cast speed and projectile speed. We take inquisitor as our asdency. On your first lab, take Sanctuary while you are standing. Still, you have concentrated ground and the enemies will take incresed damage. On your second lab, take Pious Path. Now the conetrated ground will still active if you move around. On your thrid lab, take Righteous Providence. You have incresed critical chance per you lowest Strenghth or Intelingence. On your last lab, take Inevitable Judgement. Your critical strikes will ignore the enemy, elemental resistance, gem and gem link.
Releated:POE 3.20.2 Patch Notes Preview
