This build can be VERY SYNERGISTIC when used correctly!
1) Upon final blow with the UNBREAKABLE ability, VOID OVERSHIELD and CURE will grant you bonus Darkness Transcendence energy through the Facet of Sacrifice Fragment! Having the Firepower mod slotted on your gauntlets will grant you an Orb of Power -- which gives 2x Void Weapon Surge and an additional chunk of healing from the Recuperation mod on your leg armor! This same Orb of Power will also make you RADIANT through the Radiant Orbs artifact mod!
2) Since the UNBREAKABLE ability consumes Grenade energy, final blows with it grant Volatile Rounds to your Void weapons through the Facet of Bravery fragment! These same final blows also CURE you through the Facet of Mending fragment! Defeating enemies with The Recluse while having Volatile Rounds will grant a longer-lasting VOID OVERSHIELD (Enhanced Repulsor Brace) that charges your melee abilities faster and allows them to deal more damage through the Shieldcrush artifact mod!
3) Since you are now inflicting more damage to enemies, this will allow for the Knockout aspect to activate more frequently -- enabling you to deal more melee damage! Scoring a final blow while Knockout is active will generate an additional Orb of Power from having Heavy-Handed slotted on your gauntlets! The same melee final blow will also make you Amplified -- making you more resistant to incoming damage through the Galvanic Armor artifact mod and causing your grenade to charge even faster and granting it more damage through the Shieldcrush artifact mod! Yes... This additional damage is also granted to your next UNBREAKABLE ability!
NOTE: You can even QUADRUPLE the damage of your next UNBREAKABLE blast from scoring final blows with Void weapons thanks to Spirit of Verity on the Exotic Class Item and having a Void grenade equipped!
4) While all of the above is happening:
- Every final blow with The Recluse while a Light-Based super is equipped grants additional grenade energy thanks to the Indomitability Origin Trait
- Every ability used will empower the other abilities -- allowing them decreased cooldown from having Spirit of Inmost Light on the Exotic Class Item
- Having the Facet of Balance fragment grants melee energy from rapidly defeating targets with Light damage, while rapid defeats with Darkness damage grants grenade energy!
