Quick Break is a Basic Powercard in Bloons Card Storm. It restores up to 100 health for the player's Hero. It cannot raise the Hero's health above the maximum (normally 500). It can be played even if the Hero's health is full. Three Quick Break cards unlock upon completing Card Storm 101.
Quick Break is guaranteed healing that, unlike most healing cards, does not depend on Monkeys and only costs Gold to cycle out of hand. Most other healing cards require a monkey to use or have other weaknesses that limit potential healing.
Strike Bloon can be damaged to lower its healing capabilities.
Compared to Mana Shield, it's less cost-efficient and requires more gold to cycle out of hand, but it lets Heroes take much more damage, making it useful in control decks or decks that generate lots of gold like Striker Jones with War Bonds.
The extra charge allows the player to gain up to 200 HP, in 100 HP intervals. This is enough healing in most scenarios to survive against aggro decks consistently.
