This is the second variation to my Excal Umbra Gladiator's Blade.

This Build is more expensive, but packs more power and better energy economy.

I'm sacrificing build flexibility for Ability Strength to hit the cap on Gloom (95% slow cap). This build also adds Knockdown Immunity.
We get [Transient Fortitude] for even more Strength, which boosts the Life Steal on Gloom and our damage on Slash Dash and [Exalted Blade]. Radial Javelin's Augment [Furious Javelin] also scales with Strength! That means we get more melee damage per enemy hit than my other builds!

We replaced [Equilibrium] with [Archon Flow]. We also replaced Arcane Reaper with Arcane Energize to meet our energy needs forever. Alternatively, you could replace Molt Augmented and keep Arcane Reaper if you prefer more armor and healing or Arcane Strike/Arcane [Fury] for more offensive stats. These might be better options for short missions with fewer kills as Molt Augmented will likely never get enough stacks to be worthwhile.

Archon Shards: (Normal or Tauforged)

2x Amber Archon Shard for Casting Speed. (+50% or +75%)

I recommend these for Radial Javelin. It has an incredibly slow Casting Animation. You'll use it often to increase your damage due to Augment [Furious Javelin]. However, it is possible to Bullet Jump straight up and cast in air. Alternatively, you can replace these with any of the other options listed *.

3x Crimson Archon Shard Duration. (+30% or +45%)

Since we removed [Constitution] and added [Transient Fortitude], our Duration took a huge dive. We have no choice but to get more Duration from Archon Shards.

If you chose not to use 2x Amber Archon Shard. You have some choices again with your last Archon Shards:

1. Crimson Archon Shard for Strength or Duration. (+10% or +15%)*

2. Azure Archon Shard for Armor. (+150 or +225)*
