The Damaged MOAB is a Large Blooncard in Bloons Card Storm. It starts with 500 Health, but loses 150 Health immediately upon being played. Compared to a regular MOAB, it has the same Health before it gets cut, has a lower cost, reduced rarity, and has only one charge.
Despite the damage done to the bloon on play, at 4 Gold it is the most cost-effective Large Bloon, at 87.5 power per gold after its damage. This is also currently the only Uncommon rarity Large Bloon, making it affordable to budget players. However, its power is limited by its 4 delay, which leaves it quickly outclassed by higher rarity bloons, but with 2 charges it could be viable as a budget alternative.
Cards such as Necromancer and Healing Bloon can heal the MOAB back up before it is removed too quickly.
