Keratinos has a special gimmick where a x12 heavy attack adds approximately 2-3 meter range to all attacks for 3 minutes. This means [Primed Reach] is flexible, but would give a total of about 7m with 0.8 [Follow Through].

[Voruna] sets critical chance to 100% and [Keratinos] has very low base CC meaning it can only [Reach] 84% with [Blood Rush] + glad miight, meaning we do NOT need to run crit chance mods like [Blood Rush] or Sac steel.

If NOT using with [Voruna], add [Blood Rush] over [Primed Reach]

Melee Arcane:
Melee Influence allows you to spread viral + electric throughout the map and passively nuke base SP without armor strip and endurance with strip
Melee Duplicate gives highest slash DPS, swap [Shocking Touch] for [Carnis Mandible] for endurance against armor without strip
Mele Vortex is a fun way to group enemieis.
