basic rundown: standard 12x build using naramon instead of [Body Count] or [Drifting Contact].
in depth explanation: even though the [Paracesis] gets a 60% damage bonus against sentients, it has no innate umbral polarities. so, we're just gonna do a standard 12x build assuming you're running naramon, saving a mod slot in the process. we use the flat 90s and [Primed Fever Strike] because the [Paracesis] won't hit 200% status chance even with [Weeping Wounds] at 12x. however, [Weeping Wounds] DOES push it barely past 100% at 12x, so it's still useful and necessary for end game content.
side notes: the stance mod is absolutely personal preference since it's polarized for either by default, I just hate spamming the cleaving whirlwind combo. you can also easily swap the viral / heat combo for anything else you might need: [Primed Reach], [Healing Return], etc. if you're gonna use this on steel path, might be a good idea to remove the third elemental, and make sure to have at least two V polarities so you can use a primed smite mod to double dip on the damage. everyone polarizes this thing differently, since once it hits max rank, it'll have a whopping 90 capacity, so you really don't NEED five polarized slots. /rant
enjoy slaying everything in sight with this. no need to farm any prime weapons except for venkas since DE gave everyone a best in slot freebie. :3
