Build Overview

This will most likely be the fastest Spiritborn Leveling setup.

This build requires no aspects or any special gear. Just start killing monsters from level 1

We will be starting with the Centipede skills - one point into Withering Fist + Stinger + Toxic Skin from level 2 to 4.

######################################################

Build is split into 4 parts:

Part 1: Lvl 1-15: Healing Withering Fist, Healing and Vulnerable Stinger & Toxic Skin

Part 2: Lvl 15-70: Respec to Shattered Stone Rock Splitter & Unleash the Swarm Stinger with Primary Gorilla Hall + Secondary Jaguar Hall and Sky and Soil The Devourer, The Beast Within Scourge & Counterattack of the Swarm Counterattack

Focus on maxing Rock Splitter & Scourge for max damage and Toxic Skin for extra armor

Part 3: T1-T6: Thorns leveling using Shattered Stone Rock Splitter & The Beast Within Scourge and transitioning into Counterattack of the Swarm Counterattack when reaching T5-6.

Part 4: T6-T12: Transition into Counterswarm with Counterattack of the Swarm Counterattack with Harmony of Ebewaka, Ring of Writhing Moon

You can also use the standard Gorilla Main & Eagle where we get a good increase in damage from Eagle second hall and upkeep of Barrier for Vicious Shield.

If you are dying a lot Eagle Main Hall & Gorilla Secondary Hall is actually a bit better for survivability. We lose a some damage for extra movement speed, perma unstoppable, perma vulnerable, and extra armor.

Priority aspects to look out for when pushing through T5-T12:

Aspect of Infestation

Aspect of Pestilence

Aspect of Supremacy

Aspect of Kinetic Suppression

Strengths and Weaknesses

Strong leveling with little investment
Possibly Fastest 1-70
Decent transition from thorns at T4-5 to Swarm when climbing T5-T12

A little clunky when transitioning builds from T5+ into Swarm
RC doesn't come fully online until Ravager lvl 30

T6-T12

Before heading out to kill monsters, teleport to Temis, grab your mercenaries, get your warplan started and equip your pet.

You start with a gray weapon. Go out to the Helltide on Normal or PVP Zone on Hard to grind your way to level 15 to open up the Spiritiborn potential. Check the minimap for the rifts to get good XP & a lot of cinders

I left the seasonal quest for T1+ to get quick set charms during the quest line. In Penitent and below the set charms are low level charms and not the endgame set charms. You should also get Leoric's Crown and Stone of Jordan at item power 850 if you do the seasonal quest on T1+.
