I dunno, but, it doesn't matter BECAUSE:
1. Remember the changeable temperature, that goes past boiling, so, no water.
2. The turrets are on the outside of the castle, so, they would shoot you down before you could even get a drop of water in the castle in the first place (they are also waterproof because they were built to withstand the elements)
3. Did you forget about me, I kill you all for trying to take my hill, you all are now ghosts, which I turn into Jinn's when I distract you until you forget your name.
And, finally, since I killed you, I claim your parts of the hill (this counts to eceryone who was part of the attack)
That gives me 25%+(22.5%*2)= 70%
I factored out the 10% because, as Fyer said, I did not have any hill, which begs the question, why did you attack me in the first place?
