Splash Damage

What is Splash Damage?
Splash Damage is a kind of damage. This is how it works: The tower/bloon that was hit receives full damage, and the towers/bloons that are closest (but not targeted) to the target will receive 70% damage, towers/bloons that are a bit farther will receive 40% damage, and towers/bloons that are even farther will take 10% damage. Only towers/bloons within a range equivalent to a 0/0 tack shooter's range will take damage. In summary, if a attack does splash damage, the target takes full damage, and towers/bloons around it will take damage, too. The farther it is, the less damage it takes.

Attacks that does Splash Damage
By default, attacks that involves fire, explosions, and dropping lightning bolts form the sky (2/x Monkey Apprentice's lightning don't count) will do splash damage. The author of a conception can also specify if an attack does splash damage or not. (If the author doesn't specify, it follows the default rule.)
