Star level

Star level is a game mechanic for characters in Bloons Adventure Time TD. By spending character resources, characters can be levelled up to unlock permanent enhancements, more upgrades, and additional trinket and ally slots. All characters start at star level 1 and can be levelled up to star level 10, with the cost to level up increasing at higher levels.

Star level bonuses

• Levels 2, 4, 6, 8, and 9 unlock a permanent bonus for one of the character's stats.
• Levels 3, 5, and 7 unlock a new upgrade (or two upgrades in the case of Hunter Marceline at level 3).
• Levels 2, 4, 6, 8, 9, and 10 unlock a trinket slot.
• Levels 3, 5, and 10 unlock an ally slot.
• Level 10 unlocks a bonus unique to that character.
