A pretty simple and basic [Broken War] guide. 285% Crit Chance without a Gladiator Mod.

[Weeping Wounds] is replaceable with a Gladiator Mod if you want more crit. I would use [Gladiator Might], or put a Gladiator mod on my Warframe. It's also replaceable with a Riven if you have a good Riven for this weapon as it has a good Riven Disposition.

With a gladiator mod on this weapon (in the [Weeping Wounds] slot) or on your Warframe, you will go up to 323% crit rate, meaning all hits are red crits at combo 12.

The Viral Damage is here because of our Slash Procs since the weapon deals primarily slash. If you remove [Weeping Wounds], replace [Vicious Frost] with [Voltaic Strike] instead for Corrosive.

[Iron Phoenix] Stance because from what I've heard [Iron Phoenix] is the highest DPS sword Stance. If you don't want to forma that to save another forma, use [Swooping Falcon] instead.
