A slightly less powerful version of my Umbral build. Obviously not everyone will want to toss their valuable umbral forma into [Ash]. Bladestorm will trigger both Arcane Trickery and Arcane Ultimatum provided the enemy dies to the finisher and not to the bleed proc. Trickery will halve the cost of further bladestorm marks and if it doesn't proc then you have 1200 extra armor from Ultimatum to keep you alive. Currently, Melee Crescendo equipped on bladestorm does not work correctly, so either [Rising Storm] is still advised to quickly reach 12x combo again, or running the Naramon focus school to prevent total combo decay.

Optional modifications:

• Ultimatum can be swapped with Crepuscular to gain more ability strength and crit damage when invisible, either through Trickery or Smoke Shadow (crepuscular is not an option on this site as of writing).
• Trickery can be swapped with Molt Efficiency to give a total duration of 21 seconds to smoke screen so long as shields are active.
• [Rising Storm] can be swapped for the new [Teleport Rush], and regular finishers will eliminate the need for Trickery as smoke screen's duration can be kept up indefinitely. Your Shadow Clones will either need to be built for combo duration/gain, or you will need to use the Naramon focus school to offset the loss of the combo counter once the timer runs out.

Archon Shards:
Really anything you want, though I would recommend more strength, duration, and parkour velocity.
