Equipment can come in a number of levels of rarity.
  • Common (White): These are the basic level pieces of equipment you will find in the game. They provide standard attributes with no special bonuses.
  • Uncommon (Green): A step above Common, Uncommon equipment offers slightly better statistics, and some pieces may come with additional benefits.
  • Rare (Blue): Rare items present a significant improvement over Uncommon items, offering higher stats and occasionally special abilities.
  • Epic (Purple): Epic items are highly sought after for their considerably enhanced attributes and special abilities, making them powerful assets on the battlefield.
  • Legendary (Gold): Legendary is the highest rarity level, offering the best stats and unique abilities that can significantly impact your gameplay.

Understanding these levels of rarity is a crucial skill as it will guide players in decision-making and knowing what equipment they should focus on when it comes to fusing and upgrading. The best tactic in Mighty Doom is to gradually improve the rarity level of your equipment to make you stronger and more effective on the battlefield.
