Doomworm Returns
Thrown Together in Approximately 30 Minutes.
Doomworm Returns simply Readds the Doomworm as a random encounter in the last biome, with a 20% chance of spawning, or a Mission to hunt an Abyssal, that may turn out to be the Doomworm. (You can tell because it pays over 10k by default)
Let me know if theres any bugs. Mod was thrown together quite quickly.
