"Bowl over your enemies with this rumbling ball of ice! Tap and hold to see in which direction it will go."
The Snowball Scroll can be built at the Scroll Statue and upgraded in the Ancient Temple to increase the damage it deals to both enemy buildings and troops. Upgrades will also increase the coins cost per scroll. The Snowball Scroll was added during the holiday update, along with levels that are required to pass in order to unlock it.
