Reaper equipment
You could mix marauder’s with berserker + valkyrie for extra survivability (the loss in precision from the berserker + valkyrie trinkets is made up for by the marauder’s stats).
If you wanna go condi, go full viper or viper mixed with sinister.
Idk what mode you’re talking about, but I’ll give my input on a PvE perspective (Note: currently running Axe/Foci + GS).
I currently run Zerker/Valk/Zerkerie. I personally try to place emphasis between Power, Ferocity, Vitality and Precision (in that order). Thanks to Decimate Defenses, you don’t really need much Precision. Personally, I feel like Reaper needs as much Power and Ferocity as possible, since that’s where your damage is going to come from. Zerker weapons for the raw power, Valk armor for the Vitality without sacrificing any power, and Zerker + Valk trinkets to round out Precision and Vitality. I walk away with a little over 23k Health with 29% base Precision. With max Vulnerability stacks that’s 79% Precision and with a Fury boon that’s 99%.
Marauder’s is a good choice if you don’t plan to run Decimate Defenses. I’ve goofed around with it a bit, not my personal choice but it’s not a bad option. I mainly placed emphasis on Vitality over Toughness because we’re already too squishy to risk drawing aggro and I tend to struggle more with Condis than straight damage anyways. Plus the more health you have, the larger your 90% threshold is for Scholar Runes (which, I run).
Not going into Specs unless you’re including that as ‘equipment’ but I’m going to assume you’re talking about gear in that regard.
If you run Decimate Defenses, you can usually skimp out on Precision to a point. Anything you get above 50% crit chance is effectively wasted stats.
