Almost 7 million Radial Dps with Secondary Outburst + Arcane Avenger & Arcane Precision & Pistol Aura Behind it (Highly Recommend that setup for max [Juice]).
You can also play Lazymode Cascadia Flare at 3 Million Dps if you prefer that.
The other setups I checked barely [Reach] 1.5 mill so this setup seem to be pretty far ahead in terms of dps at least.
With Avenger + Outburst ur at 99,40% Crit Chance & 6.12x Crit Multiplier. Each Tau Topaz Shard behind this again = 1+ Million Dps Pr Shard :)
''Protip'' Use [Venka Prime] to get Secondary Outburst from 13x Melee combo instead of 12 for even more giga dps :)
Or you can use [Okina Prime] Incarnon with the Seeing Red perk that grants faster Melee combo pr Slash status proc for more effective uptime.
If you absolutely [Hate] faction mods, [Scorch] is pretty competetive by just a few less million dps.
