The Elder Scrolls: Tamriel real

Forged in the fires of Oblivion and bound to a dark Daedric pact, the Hellfire Halberd is a massive weapon that ignites with green flames when drawn into battle. Its black blade, streaked with crimson veins, radiates intense heat, dealing 2d4 fire damage on hit. When you attack, two green-flamed dancing lights can immolate themselves on a nearby enemy, dealing 1 additional fire damage each.
