How to use Flash Bomb
Flash Bomb gives the shuriken +2 pierce and +4 damage against stunned bloons, and replaces every fourth shuriken attack with a flash bomb. The bomb explodes in a 40 unit radius, deals 3 damage with 30 pierce, pops every bloon type (including black) and stuns the outer layer of non-MOAB bloons for 1.3 seconds. With 0-1-3 the bomb can also distract bloons, and with 0-2-3 it strips camo.
When to buy it
On its own Flash Bomb attacks too slowly to be consistent, and its bombs often run out of pierce in the mid game. It works much better in two cases:
- As the step to Sticky Bomb and Master Bomber.
- In a Shinobi army, where extra attack speed and pierce make the stuns frequent enough for ceramic control.
The usual crosspath is 2-0-3 for attack speed (Ninja Discipline also speeds up the bomb rotation). 0-2-3 adds camo stripping, but it is a weaker DDT answer than dedicated support.
Is it worth it?
Mostly as a stepping stone. With Shinobis it is decent support; alone it is not worth $2,250.
Frequently asked questions
Can Flash Bomb pop lead and black bloons?

2-0-3 for attack speed, or 0-2-3 if you need camo stripping.
How much does Flash Bomb cost?
$2,250 on Medium. All difficulty prices are on this page.
