Double Attack is a keyword effect in Bloons Card Storm. It causes a Bloon to hit the opposing Hero two times if it leaks instead of once, effectively dealing double damage if each hit is uninterrupted. Hero Protection only blocks the first hit, and Corvus Academy of Arts consumes one Ammo per hit, but Monkey effects that trigger On Leak, such as the Heart of Vengeance Druid's effect, only trigger once. On the Bloon track, the icon that indicates how much damage Bloons at zero delay will deal to the opponent factors in the double damage of Double Attack Bloons, as if they have double health.
Triple Attack is a keyword effect similar to Double Attack, except it hits three times instead of two, dealing triple damage if uninterrupted. The only Bloon with this keyword is the Triple Threat Bloon.
