# Snow Angel

Snow Angel can protect your snowballs from being swapped (you can still swap with others and be pushed into the Abyss).&#x20;

At the beginning of each term, there will be Snow Angels available for calling. Users can pay $AA to call a Snow Angel to protect one snowball until the end of the term. The maximum number of Snow Angels is equal to 20% of the number of snowballs in line.&#x20;

The price of calling a Snow Angel will be  8 $AA at the beginning of each term, and it decreases by 1 AA every hour.

No matter when you paid, the Snow Angel can only protect your snowball till this term ends. When a new term starts, you need to pay again to call for the Snow Angel.&#x20;
