Skill Synergies and Mechanics
Rive
Doubles our damage and ailment chance with Foe Cleaver 1/1. This is huge for Shred Armour as even a t5 will quickly allow you to reach the maximum amount of effective stats. The Temporal Warrior 1/1 node is great, but you do not even need to be a Void Knight to use Foe Cleaver 1/1 to great effect. We take Focused Strike 1/1 as a key part of this build to not care about crit chance on weapon or gear, which allows us to focus on attack speed and other important damage stats. Weapon Specialist 1/1 provides us some nominal void damage to scale with the Void Knight's innate void damage synergies, and is a good reason to take PrefixVitality when you can.
Anomaly
30% SuffixIncreased Cooldown Recovery Speed (including to anomaly itself) with Swiftrest 3/3, and with even a t5 cooldown mod on boots you will have 100% uptime. Important contributions here are attack speed (can't get enough) and 200% SuffixIncreased Leech Rate, which when combined with the 130% from Siphon of Anguish and Apathy's Maw translate to our health bar snapping back to full at warp speed every time we take a hit that doesn't kill us.
Abyssal Echoes
This is a damage multiplier, Attack speed booster and also grants us Shred Armour chance, Physical penetration, and Time Rot chance. Abyssal Echoes packs a pocketful of sand to debuff your enemies with as well as buffing ourselves considerably with Embrace the Darkness 4/4.
Void Cleave
Our traversal skill that aids Abyssal Echoes in debuffing the enemy, instantly applying multiple ailment stacks and in unison with Abyssal Echoes allows us to reach more than acceptable levels of Shred Armour (which multiply our damage greatly).
Volatile Reversal
Unlike most builds which use this for mana restoration, we are using it purely for damage and can take Timelost Wisdom to shorten this cooldown to about 4 seconds under the effects of Anomaly. You can play around with extending your reversal with Ancient Reversal to match the cooldown timer,but 4 seconds is longer than you think and this can easily land you in trouble, so exercise caution. In addition to letting us reposition cleverly by going back in time, this skill amps our damage considerably when both of the rifts created hit the same enemy (they are visually underwhelming and hard to see, just make sure you ender and exit the Volatile Reversal on top of the enemy).
Using the Skills
Anomaly
This is always on, I keep this on left trigger and clamp it down. It shouldn't interrupt you too much after the cast speed from Blademaster 5/5 kicks in. You can try to aim it but currently it is not worth the effort on controller.
Rive
ABR - "Always Be Riving." Controller users will find it fairly easy to stutter step across the battlefield dragging enemies with Challenge to more opportune locations and circle strafing to dodge fire. I can't seem to do it very well on mouse, but many are more skilled than I.
Abyssal Echoes
ABCA- no not that. "Always Be Casting Abyssal Echoes". you will be limited by mana early and your will to press this many buttons later, but eventually you can also just hold this down and rely on Rive and Time and Faith 3/5 to keep your mana healthy.
Volatile Reversal
If you ain't reversin', you are...worsen...ing. Uhh, anyway, you should also cast Volatile Reversal as often as possible and if you have paddle buttons or particularly dexterous fingers can just hold all 4 of these down in the endgame. 2 seconds at base should be plenty but you can increase this with Ancient Reversal if/when you are confident in your ability to not make every skill press your early grave.
Void Cleave
FINALLY, you think I wouldn't give you a skill with some agency? void cleave will get you around, but also you should weave this in as often as possible* to your rotation due to Armor Sunderer's increased armor shred duration and effect. it's also a good way to stack Time Rot for Food for Wyrms 4/4*.
*Controller users: This will occasionally and unpredictably shoot you way past the target, which is deadly in some boss fights. You may need to hold off in some cases.
**Before you have an Apathy's Maw, you want to avoid this since it only boosts void damage.
