Scourge is a Daedric artifact tied to Malacath, known from Battlespire and Morrowind. The Cause Creation sends you into the Deadlands, the realm of Mehrunes Dagon, where a Dremora lord wields it.
How to get it
During The Cause, the Dremora Valkyn Gatanas uses Scourge in the Deadlands. Defeat him for the final time and loot it from his body. Since game update 1.6.629 he also carries the Daedric Gauntlets of Negation.
Enchantment
Banish: summoned Daedra up to level 36 are sent straight back to Oblivion. That means one hit removes most atronachs and Dremora that enemy mages summon.
Stats and handling
18 base damage at a weight of 22 – more than a Daedric Mace. It uses the One-handed skill.
Smithing
Improve it with an 
Ebony Ingot. It needs Arcane Blacksmith, and Daedric Smithing doubles the improvement.
Strengths and weaknesses
- Strength: more base damage than any base-game mace.
- Strength: deletes summoned Daedra.
- Weakness: the enchantment does nothing against anything else.
Tips
- Brilliant in the Deadlands themselves and against conjurers.
- Its sister weapon from the same Creation is Torment.
