Infernium [CARD] (Patreon)

Weapon (greatsword), very rare (requires attunement)

You may use a bonus action to rev the handle of this magic weapon, causing flames to erupt from the blade. These flames shed bright light in a 40-foot radius and dim light for an additional 40 feet. While the sword is ablaze, it deals an extra 2d6 fire damage to any target it hits. The flames last until you use a bonus action to pull the handle brake or until you drop or sheathe the sword.

Rev It Up! When you hit with a melee attack with this weapon, you may use your bonus action to rev the throttle, igniting the sword further at the moment of contact. Make a DC 10 Dexterity check. On a success you deal an additional 2d6 fire damage.  If you succeed on this roll, before you deal the additional damage, you may use your reaction to roll a DC 15 Dexterity check. On a success you deal a further 2d6 fire damage, on a failure, you cause no additional damage with Rev It Up and the sword is extinguished.

Full Throttle. You may use your action to balance atop the blade, revving the throttle and bursting forward with great force. You move in a straight 60-foot line spinning the blade around you. Creatures within 5 feet of the spaces you move through must make a DC 15 Dexterity saving throw. They take 1d6 slashing damage and 2d6 fire damage on a failed save and half as much on a successful save. Once you use this feature, you cannot use it again until you finish a long rest.

The terrifying mechanical horrors found within the circles of hell generally strike only fear in the hearts of those who see them. However, where some find only terror, other more unhinged individuals may find inspiration. This is how one such engine found itself affixed to a gruesome greatsword. The designer clearly had no sense of subtlety, attaching the remains of a devil to the blade. Gaudiness aside, those who wield this blade are sure to have “One hell of a party.”
