Diamond Lances create Stasis crystals on impact when thrown, with more crystals created by hitting bosses and vehicles. While using a Stasis subclass and behind your rally barricade, rapid precision hits and combatant final blows with a Stasis weapon creates a Diamond Lance near you.
While a Stasis Super is equipped, rapid Stasis weapon damage or damage from behind your Rally Barricade will create a Diamond Lance near you. Thrown Diamond Lances create Stasis crystals. Your Diamond Lances deal more damage based on how much Frost Armor you have.
