Chromatic Blade needs 189% strength to have over 100% status chance on your Exalted Umbra Blade (same as the standard), so while 192% is cutting it close, you can get more if you proc Growing Power before casting any ability
IMPORTANT: Get an EMISSIVE COLOR FOR COLD, that way you benefit from Archon Flow for energy economy (I'm looking for a different Energy source without sacrificing damage/survivability to use Archon Vitality and Heat damage instead)
Either way, you can deal massive amount of damage with wrathful advance and it pairs really well with [Furious Javelin] giving you a massive damage boost on top of that
Ideally I'd swap [Continuity] for [Narrow Minded] to have more ability duration (QoL more than anything) but you loose range which affects the reliability of Radial Javelin
So yeah, if you don't like it just change it up a bit, we play for fun after all :)
Archon Shards:
1 Tauforged green for up to 98% Armor Reduction from Corrosive Procs (Exaulted Blade)
(1 Tauforged green = 98% Armor strip, 2 standard = 100%)
4 Tauforged Purple for Extra Melee Critical Damage, which with a max Energy of 641, gives you +300% Crit Damage on your Exaulted Blade
This is by far my favourite build not just for [Excalibur], but in the entire game because you can deal millions of damage per hit with pretty much no downsides (besides maybe survivability in Endurance) since I have Life Strike on my Exaulted Blade to heal with heavy attacks (Slam Heavy attacks count too, so you can ignore wind up speed!) which is far from the meta but incredibly fun to play, Furious Javelin scales infinitely and you reliably get kills with Exaulted Blade easily, so you get more energy than you use allowing you to spam Radial Javelin if needed.
Easily demolishes SP enemies of any level as long as they don't one shot you first, on the Circuit getting Overguard per melee kill will massively boost survivability since you'll benefit from Shield gating from Overguard!
Long story short, this build is a powerhouse
