Keep popping the Mini Boss.
Reach the goal to earn rewards.

— Message that appears when selecting a Mini Boss tile

Mini Boss is a type of tile in the Rogue Legends DLC for Bloons TD 6. They are similar to Mini Game tiles in that they are optional challenges that reward an Artifact upon completion, with the rarity depending on which of the three score targets the player manages to reach. Unlike Mini Games, these tiles use Boss Rush mode. The boss is randomly selected, indicated by the Boss Bloon circling above the tile in a similar way to Boss Tiles in Contested Territory, and it can be any boss except Vortex.

The boss starts with 200 health, increasing by 15% multiplicatively each time the player pops it. If the boss has a shield, the shield starts at 65 health and scales in the same way. The player starts with $2,500 plus the starting cash of the current difficulty. The boss rewards $500 when popped, increasing by 2% multiplicatively each time the player pops it. These tiles use the endurance round set rather than the usual Rogue Legends rounds, and Powers are usable normally. The player earns a Boost upon starting the first round and every 5 times they pop the Boss Bloon.

The goal the player reaches determines if the Artifacts they can choose from are Common, Rare, or Legendary. If the tile has a Legendary Augment, they can choose two Artifacts of the same rarity, each from three options. The goal also determines the amount of Rogue XP the player earns (after the stage-based multiplier).

  • Common: 10
  • Rare: 20
  • Legendary: 25

The editor who added this notice elaborates: Determine if the score scaling is correct after the changes in version 49.0.

Each Mini Boss tile has three score targets that determine the type of Artifact the player earns. The number of boss pops required to reach each target depends on the stage number. In CHIMPS mode, all target scores are 10% lower.

Common Rare Legendary
Requirement 7 + 3 per stage 22 + 3 per stage 32 + 3 per stage
Rogue XP earned 9 + 1 per stage 18 + 2 per stage 22.5 + 2.5 per stage, rounded down
