In many strategy games, victory is determined by who possesses the strongest army or the most resources.

In the classic arena battler layout, the map is divided by a river with only two small bridges serving as crossing points.
The Ultimate Choke Point
This predictability allows you to pre-aim massive splash damage spells and position your defensive buildings optimally.

If you play your defense too far back, the swarm spreads out, rendering your splash damage virtually useless.
Use cheap units to physically block the bridge.Beware of flying units; they ignore the bridges entirely.Deny them space. Funneling with Buildings
This technique, known as funneling, allows you to dictate exactly where the final engagement will take place.

Right behind that artificial gap, you place your highest damage-dealing unit to instantly delete anything that squeezes through.

When you perfectly control the choke points and dictate the engagements, the opponent will feel incredibly suffocated.

Do not just play cards randomly on the field; think about the geometry of the arena.
