See the user build section for builds using this weapon.
The Orthos will extend slighty when drawn, and retract back after "sheathing".
Being the longest melee weapon (after Orthos Prime), the Orthos benifits greatly from Reach; a maxed out Reach will allow you to hit enemies through walls, bypass Grineer Shield Lancer's shields, and strike Toxic Ancients without touching the poison cloud.
Combines with Ash's maxed Smoke Screen or Loki's Invisibility for devastating attacks.
In Greek mythology, Orthos (also known as Orthrus) is the name of a two headed dog, brother of Cerberus.
