Earlier, I was expecting more, but...
Towers destroyed: 3/3
Main Guild Destroyed 0/1 (Optional)
Leader killed: 0/1
I already depleted all of their towers and the only remaining thing I needed to do is destroy the main guild's headquarters or kill the guild leader. Since the purpose of this battle is to destroy the Blue Sky Guild, destroying the main guild's headquarters is also included in my agenda. Sure, they poured a lot of money to the guild's headquarters but so what? Do I have to care about that? After all, it's not my choice for them to invest a lot of money only to end up being washed away from a battle.
After destroying the last tower, I waited for a bit to see if they have the reinforcements to back up the remaining players trying to salvage what was left from the final tower but no one came so I ended up dealing with all of them and killed them all after I got bored waiting.
Time for the final boss I guess?
