(OLD SYSTEM) UOG: Demise - Doom Boss Artifact Drop Chance

Calculate the drop chance for:
Dark Father
Other Gauntlet Boss

When the player who does the most damage to the selected boss has luck, and other characters¹ earned looting rights on the boss, my chances of receiving an artifact are...

Important facts to consider when thinking about gauntlet drops.

• The chance that a boss will drop an artifact is affected by the Luck of the player who does the most damage to it.
• If a boss ends up dropping an artifact, it is randomly given to one of the players who earned looting rights on the boss. In-Game Luck plays NO factor in actually receiving an artifact if one is dropped.
• Most players have no idea what they are talking about when they explain Gauntlet drop rates, don't believe them.

¹ This number is in addition to yourself. So enter 0 if you are the only player with loot rights to the boss.
