[Shattering Impact] vs. [Killing Blow]? I think so. It sucks to lose damage, but you more than make up for it by reduces their armor to nothing with [Shattering Impact].

Relentless Combination vs. Body Count? I think so. It sucks to lose combo duration, but you more than make up for it with the built-in range passive of the [Keratinos], and well as the aamzing rate in which you gain combo counter with [Relentless Combination].

[Strain Infection] over [Amalgam Organ Shatter]. Wind up speed isn't needed, and you actually get more crit damage with Strain Infection than organ shatter.

Crit, slash, impact, heavy attack viral build. Damn.

How to fit in CO for full Crit/CO hybrid damage?

[Shattering Impact] vs. CO? CO is better? I think so. Also better than [Killing Blow] since MUCH more damage and wind up speed not needed.

CO over [Sacrificial Pressure] over [Primed Pressure Point].

Does Empowered Blades replace weeping wounds? I think so. Empowered Blades+status chance from Carnis and Saxum make this okay.

Berserker/attack speed not needed since Warcry subsume exists.

How to Own Nerds: Keep Warcry on constant while using [Keratinos]. Use [Xaku]'s Whisper on cooldown for constant crazy ass melee buff damage. Heavy attack big targets.
