Nice to know
U can also spent more normal Forma to save the umbral Forma.

To make [Energy Conversion] more useful use a [Dethcube Prime] with his special Mod that allows him to Drop Energy Orbs after 10 Assists.(Build uploaded on my Profile for it)

use as much Crimson Shards as possible :) More Ability Power = more Stacks on Mesmer Skin AND more DMG on Eclipse.

Dont be afraid that u dont have [Sure Footed] on because Mesmer Skin IS [Sure Footed].

Maybe use Madurai for even more Ability Power.

[Thrall Pact] is on helpful in some Situations but its getting WAY more useful at high lvl Enemies( the higher the better)

The low Efficiency is not a big issue since 1. U dont spent that much Energy and 2. with [Flow] and Energize u wont have any issues.

The Aura is exchangeable.

Why did I change the 4th Ability for Eclipse?

Why not the First? : simply because of [Thrall Pact] and it synergizes perfect with Mesmer Skin!

Why not the Second? : Do I rly have to tell? IMMORTAL

Why not the third? : firstly because it synergizes with Enthrall because u have an over 100% life drain which means u can basicly 1shot everything that is not a boss or similar. This Ability is the most arguable but with my experience Danse Macabre is just not viable in a bit higher lvl enemies.

Equipment:
Primary: Pick whatever u want to use :)

Seconday: Also Pick whatever u want :)

Melee: [Vastilok] build on Armor Strip (Ive uploaded a good Armor Strip build for it)

Why [Vigorous Swap]?
The DMG buff triggers when using a simple melee attack, which u have to use anyway when u strip the armor with the [Vastilok].

My personal reasons why this build is INSANE
WIth his build u are unkillable AND u deal TONS of DMG. Being able to change u weapons in whatever u want is just amazing cuz u dont get bored.
