Custom Don't Starve boss since I've been playing it a ton. Wendigo can be fought as an alternative to Deerclops during Winter, and can very rarely be found during Fall (if Wendigo is killed before Deerclops spawns, Deerclops will not spawn; however, killing Deerclops does not prohibit the spawn of Wendigo). Wendigo can rarely spawn during night in Winter, but only if you're in a dense forest biome; a Wendigo spawning is signified by coyote yells being quietly heard while in the woods. Or, can be manually called with a Hunter's Horn during night in the woods in Winter. Wendigo can be seen as a harder Deerclops, with more health and similar behavior. The Wendigo can perform a large claw swipe, let out a loud screech which can disarm the player, or stomp on the ground on all fours to create a small shockwave. However, Wendigo can also slam it's bag down and begin rummaging through it. If not interrupted, it'll heal itself by getting new pieces of bones from his bag. The Wendigo drops many bone shards, and inside his bag are more bone shards, a lot of nightmare fuel, a Deerclops Eye, and occasionally Living Wood. Additionally, the bag dropped after death can be dragged around, and be used as a large chest.
