🔥 Check out the video for full showcase & accurate gear info 🔥

Hope you enjoy this build guide! We are still new to this since we mostly only do showcases, but your support will motivate us to do better! Cheers

Strengths and Weaknesses

  • Melts the hardest content in game
  • Satisfying ARC Chains
  • Off-screen clear
  • BIG BURST DAMAGE on any bosses
  • Consistent mana sustain + DPS
  • Super expensive (Min-maxed AF)
  • Might get lag sometimes due to too many ARC chains (at least for me)

Build Variants

This build is fully optimized for Gemling Legionnaire only!

⚡We are abusing Arc damage by stacking tons of chains (Thanks to Advanced Thaumaturgy, which gives %More damage per remaining chains on ARC)

⚡With Dominus' Grasp + alot of gem quality%, we're able to hit 50 CHAINS!

__________

(Other options)
Snakepit is a good budget option if you could not afford a Loreweave with +2 chains.
Can even get a high ES chest armor for more tankiness as well.

Use Ingenuity instead of Mageblood, but u gotta invest more into crit chance (Make sure to hit at least 80%)

( Cheapest option to scale crit )
1. Use Maligaro's Virtuosity + Pinpoint Critical, then replace all Critical damage bonus nodes to any other damage nodes(Spell,Elemental, etc)

How it Plays

Basically use Arc and it will trigger more Arc, and you will get a whole screen of Arc.
This build is specifically using Arc for all content - Mapping & Bossing.

Make sure to stay close to bosses to insta-melt them. Why?
1. Spellslinger with living bomb will generate lightning infusion
2. Consume lightning infusion to deal 200% more damage + more chains = more more more DAMAGE!

Mana Tempest + Sigil of Power = GG DPS BOOST

Numlock trick to constantly trigger Spellslinger, or u can just hold down the button.

How it Works

How to generate infusion?
1. Living Bomb (Fire infusion) + Elemental Equilibrium = Lightning infusion
2. With Spellslinger , u basically just aim whatever direction and it will trigger Living Bomb, thus giving you infusion after hitting the target.

How to generate power charges & why do you need it?
1. With Infusion of Power (Annoint), you will consistently having it since you're consuming infusion all the time with Living Bomb.
2. We need power charges for HUGE Crit boost from Charge Regulation.
(You can also annoint Thaumaturgic Generator for all 3 charges)

Since we're focusing the main damage on our self-cast Arc, it will deal insanely high damage, thus easier to trigger Cast on Critical .
