Arc of Surging
Inquisitor build

Updated for Patch 3.23

The Best Crafty Guides by Odealo

The new Arc of Surging is a very intriguing Skill. It drastically changes the behavior of the regular Arc, instead of Chaining between nearby Enemies it will Split towards 9 targets after Hitting the first Enemy. By default, it is actually a weaker variant of the regular Arc, as the Damage doesn't scale with amounts of remaining Chains. However, its unique interaction with the Hydrosphere Spell allows it to Split all additional beams toward a single Enemy, improving your Damage tenfold, which makes it one of the best Single-target abilities in the game. 

As mentioned, the concept of this Build relies on the Hydrosphere. It creates a stationary Orb that can be targeted by your other abilities, but you can Hit it only once per second. It also applies Cold and Lightning Exposure to nearby Enemies. The Arc of Surging will Split up to 10 times upon Hitting the Hydropshere, and all Splits will be targeted at nearby Enemy. The additional repeats from the Unleash Support bypass the Hit Cooldown of the Hydrosphere, for a total of 40 Hits per single Cast. You can further increase the amount of Seals for even stronger Burst, but you will also have to wait longer for their recharge. 

This playstyle is rather restrictive in terms of scaling your Damage. You don't need any Cast Speed, instead, you should emphasize dealing very high amounts of Damage per Cast. Additionally, the Arc of Surging has a rather good effectiveness of Added Damage. All things considered, the best option for this setup is to use Energy Blade and Spellblade Support to add massive amounts of Lightning Damage to your Spells, sourced from your Energy Shield. Arguably the best Ascendency option for such a style is the Inquisitor. It provides the Battlemage effect, which has the same effect as the Spellblade Support, i.e. adds the Damage of your Weapon to your Spells. The Inquisitor also allows you to very efficiently scale your Energy Shield, Critical Strike Chance, and Damage by stacking Strength and Intelligence. Furthermore, it provides a great defensive value of constant Regeneration.

1. Gameplay

You will start the fight by summoning the Hydrosphere. You shouldn't place it too close to your target so your cursor doesn't accidentally lock on the Boss instead of Hydrosphere. The Arc of Surging will Split upon hitting the first Enemy. To weaken your foe you shall use the conductivity and Elemental Weakness Curses. 

2. Build's PROS & CONS

3. Leveling tips

The final setup requires many end-game Items, we would advise leveling your character as a regular Spell Cast. The Arc of Surging can be used as soon as you acquire the Hydrosphere, which is at level 34. You should check out our Leveling Guide for Templar using Lightning Spells for more tips. 

Bandits:

Killing all Bandits for 2 bonus Skill Points is the best option, the Build is very Passive Points starved.

5. Gear Setup

The Build consists of many mandatory Unique Items, which are used to boost your Energy Shield. The majority of your Energy Shield comes from the Ivory Tower Armour, which grants you flat ES based on the amount of maximum Life you reserve with your Auras. Scaling maximum Life also synergizes very well with the Rathpith Globe Shield, which grants you an insane amount of Damage and Crit Chance. You will also use the usual Attribute-stacking Unique Items such as Cyclopean Coil or Eyes of the Greatwolf. On the very few Rare Items you will wear you should aim for lacking Resistances, Attributes, maximum Life, or Spell Suppression. To improve your Damage via other means than Attributes you should focus only on the Critical Strike Multiplier. Most of your Resistances will be sourced from your Flasks, but you might need some of them on your remaining Rare Items as well. 

(Helmet) Crown of the Inward Eye - improves your maximum Life and Energy Shield, which is very important for this Build. The Transfiguration modifiers also scale your Damage a bit.

(Amulet) Eyes of the Greatwolf - later you should replace your amulet with this Unique talisman. it can grant you up to 32% increased Attributes, but even the lower rolls are worth it, especially if you match it with other useful modifiers such as Global Defenses, Crit Multiplier, or Physical Damage Reduction.
