The Snowstorm Invasion

The Snowstorm Invasion is an event that has a 1/3 chance of happening in Hardmode when the player has defeated Duke Fishron, or when summoned with the Snow Amulet.

Structure
The Snowstorm Invasion is made up of several waves of snow-related enemies, ending with the summoning of the Frost Titan. The waves each contain random enemies from the event, but easier enemies come before the harder ones.

Enemies

 * Frozen Soldier
 * Ice Shaman
 * Bear Rider
 * Polar Bear
 * Mounted Archer
 * Snow Mage
 * Ice Gargoyle
 * Snow Summoner
 * Snow Spider
 * Frost Titan (Boss)

Aesthetic Changes
In Snowstorm-occupied territory, the ground changes to snow, ores freeze over and cannot be mined, and snow falls.

This is reversed when the Invasion is defeated.
