Build Overview

⚡Strongest self-cast SPARK (Non-CoC) Gemling
⚡Almost unkillable!
⚡10/10 clearspeed & bossing

Disclaimer - This build is perfectly min-maxed. If you're on a budget, other ascendancy will be a better option as its easier to scale.

Strengths and Weaknesses

No-Brainer JUST Spark build (No CoC)
Literally melts every juicy content in 0.5
Insanely tanky (Almost unkillable)
All-rounded build + no hidden tech/CoC

Expensive to reach this level (Perfect mana sustain, damage, tankiness & speed)

Build Variants

There are many different builds for Spark , especially the meta CoC ones.
But as for my Gemling Legionnaire version, i wanted to make a no-brainer build that only uses Spark to do everything without any Cast on Critical or trigger shenanigans.

This build is purely min-maxed as the perfect SPARK CASTER with :
⚡Perfect mana sustain
⚡Giga DPS & Fast clearspeed
⚡Insanely tanky
⚡Chill playstyle (Zoom Zoom > Spark > everything dies)

How it Plays

(Lazy 1-Button gameplay)
Spark alone solo everything, even the juicest content in game!

(Overkill DPS Boost)
Mana Tempest , Flame Wall & Sigil of Power gives a huge boost on damage, but its not mandatory to use if you're min-maxed enough.

Orb of Storms + Elemental Equilibrium = Ice infusion = giga Spark DPS

How it Works

This is a mana-stacking Archmage build.

Offense
⚡Low life tech using Atziri's Communion + Pain Attunement = Insane Crit damage bonus BOOST
⚡Stack tons of mana (At least 5k) for decent %extra lightning damage
⚡+Lightning/spell skill level is IMPORTANT for maxing out DPS
⚡Be sure to hit ur crit chance as high as possible since our crit damage bonus are gonna be around 1k+
⚡High cast speed = more proj speed (thanks to Vilenta's Propulsion)

Defense
⚡Since we're stacking a huge ton of mana, Mind Over Matter is the best pick for tankiness (but u gotta invest alot on mana regen, also %mana on kill is MANDATORY to stay full mana most of the time during mapping)
⚡If you wanna lose some damage n go Chaos Inoculation, it works too!
⚡ Blasphemy + Temporal Chains also helps making you unkillable since nothing can touch you most of the time.

_____

Why Gemling Legionnaire?
1. Tons of benefits from alternate gem quality (Advanced Thaumaturgy) such as spirit reservation cost, mana regens, more damage, etc.
2. Gem Studded helps a huge ton on mana cost sustain as well
3. Implanted Gems are huge for the extra +2 level on non-spell/skill gems
4. Essence of Virtue boost up mana regen too!

Basically, gemling is an all-rounded ascendancy and it's very strong in 0.5!
