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

I'm sacrificing build flexibility for Ability Strength to get closer to the cap on Gloom (95% slow cap). This build also adds Knockdown Immunity.

Archon Shards: (Normal or Tauforged)

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

You need 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].
Alternatively, you can replace these with any of the other options listed *.

2x Tauforged or 3x Crimson Archon Shard Duration. (30% more Duration)

Since we removed [Constitution], we have to get more duration from Archon Shards. (Total 125% Duration)

If you use 2x Tauforged Crimson Archon Shard. You have some choices again with your last Archon Shard:

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

2. Amber Archon Shard for more Casting Speed. (+25% or +37.5%)

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