This build almost has no cooldown when facing alot of mobs since fleche reduce 15% cooldown on kills and now has AOE from essence of void and addtional charges from virtue
Essence of void as main damage dealer (AOE huge physical dmg) that proc on fleche basic attack trigger, upgrade as much as needed
Essence of Virtue increase charges for more fleche spam upgrade to 150% for 2 additional charges (5 charges is enough)
Essence of clemency are optional use it for survive or swap with another to deal more dmg (Essence of dusk)
Chaos : mainly take attack power and sometimes health to avoid 1 shot
additional skills :
Rewind - great for killing bosses (spam fleche then rewind and spam again)
Umbral edge/arrow storm - Dish out more damage, Fleche trigger them
Parry/Repulsive shield - might sound weird but trust me once you understand the bosses moveset THEY CANT DO ANYTHING with this skill in hand
