The Enemy Base. If you attack the enemy base, you will have an increased chance of OSRS Accounts attacking it for each part you control. Each area they control increases the defense of the base. You can take down the fort if they have control of the entire battlefield, but it's not an easy task. After attacking the enemy base you are given the choice of either destructing the catapults/ballistas or turning them into your own. Your base must supply ammunition for the ballistas for loading the ballistas.
Catapults should be loaded with rocks from nearby or bombs from your base. You can attack enemy bases with a batteringram that you have at your home base. When you attack the fort of the enemy, their NPCs will pile upon you.
The Tower Rangers and Fortress Mages that appear in the fortress will shock you with arrows, and they will barrage you with; ice, shadow or smoke to be exact. Battle Mages will use blood barrage if their health is less than half. This means that you should be ready to fight if you decide to go this way to victory.
When the walls of an enemy base are weakened that you can go through, you are able to enter. Be wary of Vanguards, they will make things difficult. You can also use a tinderbox to deal with the base's damage at various stress points. You can put out your enemy's fires using water in a bucket that is mixed with water. If your base is destroyed or all 180 NPC fighters are killed and you are victorious, you will win.
