Clash of Clans adds a new battle spell and advanced warfare in the latest update. It's getting chilly, because you can now cast a new freeze spell that freezes enemy turrets and ground troops, disabling structures and immobilizing troops. Also available is a level 5 factory spell, level 6 lightning spell, and level 6 heal spell.
As for the advanced warfare, you can now crush your enemies with P.E.K.K.A level 4 and also upgrade your cannon to level 12 for even more firepower. Protecting walls and clearing airspace is also easier with level 11 walls and an additional air bomb and seeking air mine. More gameplay options are also available along with tweaks to the interface and balance of gameplay.
