Attrition is the COBRA's path 2 tier 2 upgrade in the mobile version of Bloons TD Battles. Every round, the COBRA steals 2 lives from the opponent and, in return, generates 2 lives for the player. If the opponent has 2 or fewer lives, it instead generates $50. Attrition has a 15 second cooldown and only occurs 3 times per round. Despite what the description says, it does not only generate lives without also stealing lives.
