Okay kiddo, so let's say we are playing a game where we have to attack a big building called a tower. But the tower is very strong and has lots of different parts to it that we need to attack in the right order to make it fall down.
To do this, we need to "target" specific parts of the tower. This means we aim our attacks at a specific point on the tower, like a window or a door, instead of just hitting the tower randomly.
When we attack a part of the tower that is weak, it takes more damage and gets closer to falling down. But if we attack a part that is strong, it won't do as much damage and the tower will stay standing.
So targeting towers means we aim at specific parts of the tower in a certain order to make it fall down faster. It's like playing a puzzle game where we have to figure out the right way to attack the tower to win.
