Many frost attacks split into smaller pieces upon impact. There are three types: ice, frost, and snow. All three of these, if they touch an Arcanist or minion, will disappear and do damage. If frost touches the ground, it will leave a small hole. If ice or snow lands on the ground, it will pile up. If snow lands on water it will form land. Ice and frost both do 5 damage, whereas snow does 2. While frost minions and ice towers are hurt by both ice and frost, snow will heal them.
