Frost Legion



The Frost Legion is a Hardmode event during which unique Snowman enemies spawn and swarm a player's spawn point, similar to the Goblin Army (though much harder). The drops listed assume the player has at least 200 health.

Unlike the Goblin Army, the Frost Legion can only be initiated by the player, using the Snow Globe. The Legion will never invade on its own.

Once defeated, the Santa Claus NPC will be available and will move into an empty home, but will only be present from December 15th-31st (in the, Santa Claus appears on those dates even if the Frost Legion has not been defeated).

A world does not need to be in Hardmode in order to summon the Frost Legion, nor to acquire the Santa Claus NPC, however Hardmode is required in order to acquire the Snow Globe that summons it. Since the Frost Legion enemies are intended for Hardmode armor and weapons, it is not advisable for those without such gear to summon a Frost Legion.



Initial event
When summoned, a message will appear: The Frost Legion is approaching from the [east/west]!

The direction specified in this message only pertains to the initial wave of Snowmen, which spawns at the World's edge and travels to the player's original spawn point. Additional waves spawn immediately within the player's original spawn area. If the message says "West", the Snowmen will come from the left. If the message says "East", they'll arrive from the right. Note that these directions are not related to the apparent motion of the Sun and the Moon, which, in Terraria, appear to move from left ("West") to right ("East").

When the Frost Legion is about to begin spawning around the player's spawn point, the following message appears: The Frost Legion has arrived! and the theme music will switch to the "Boss 3" theme.

Completing the event
The event is completed when all the Snowmen in the legion are defeated. There will be 80 Snowmen, plus an additional 40 for each player that has a maximum health of 200 or more. In single player, the army will consist of 120 Snowmen, while in an 8-player game, with each player having 200 HP or more, it will spawn 400 Snowmen. With the maximum of 255 players above 200 health, the maximum number of snowmen in an invasion is 10,280.

When the final wave of Snowmen is on the screen, a message will appear saying, "The Frost Legion has been defeated!", and the theme music will return to normal.

Tips

 * As in other invasions, if you're far enough underground, the snowmen won't spawn, even after getting the message that they've arrived. This means you don't have to head back to your house immediately upon receiving message of an imminent attack. However, the invasion will remain and the snowmen will appear if you surface.
 * The Snowmen are incapable of jumping down from simple platforms.
 * The Frost Legion tends to leave placed Snow Blocks everywhere. You may wish to fight them some distance from your base, to avoid having to "clean up" afterward.

Trivia

 * A fourth Snowman sprite is available in the game resources, with dynamite lodged in its head. It is not used in the game, likely for the damage to blocks that it would cause. It might also not be included because it might demolish or trap its own allies.
 * The changelog of 1.2 stated that the Frost Legion is back, now with another member, so this might have been planned to be added again.
 * " Do you want to slay a snowman" is a joke on the famous song "Do you want to build a snowman" from the Disney movie Frozen.
 * Despite being made of snow they are immune to On Fire! and Cursed Inferno debuffs.
