Battle Experience () is a Colossingum-exclusive mechanic introduced in My Singing Monsters3.0. Battle Experience is earned by completing Quests. The Colossingum has its own levels, ranging from Level 1 to Level 30. Leveling up The Colossingum unlocks new Costumes available to purchase for Monsters for Medals and decorations available to purchase on the market for medals.
The amount of experience required to reach each level, and unlocks, are shown in the following table.
After reaching Level 30, the Battle XP counter no longer increases, and reads the overflowed (amount of BXP earned above the 28,000,000 required to reach Level 30) value out of 0 (zero).
