Major Fortifications (Structure)

Major fortifications happen when Hyrule upgrades hyrule castle 4 times which then proceeds to remove all cannons and places them with turrets much stronger and tankier than normal turrets.Hyrule castle also becomes a plantary fortress with increased hp and armor and decent attack dmg. (their is a buff to increase hp and defense of fortress it self and turrets and gates) Gates are also buffed

Fun Fact : This is sometimes known as Cancer Castle B/C it is just annoying to deal with
