Spawns at exactly midnight, Corruption Level 2 only.
Wendigo is exclusive to Corruption Level 2, spawning in snowy taiga and tundra biomes at exactly midnight, once per day. An intro sound plays, then it waits 6 seconds before moving.
It only closes distance horizontally, following the shape of the terrain rather than flying, fully GeckoLib-animated. Getting within 1.6 blocks costs 5 hearts of damage, after which it disappears.
