Steel Path [Lavos]
Slot in 2 Casting Speed Amber Shards, and 3 Ability Strength Crimson Shards for over 450% Ability Strength.
Use with Zenurik for grouping and [Cedo] for maximum Status priming.
I like to run with [Vastilok] for stripping armor from Acolytes. Secondary is up to you. [Epitaph] is not a great option for [Lavos] since it just doesn't apply status fast enough to ramp up the damage he needs. [Cedo] does that job better after all.
Companion can be a [Panzer Vulpaphyla] for extra Viral and survivability, though I enjoy [Helios] with [Verglas] since its damage ramps up pretty high against Status affected enemies.
