Ominous Phantoms changes the way Phantoms spawn; insomnia is no more! Now, if you try to sleep at night with the Bad Omen effect applied, it'll transform into Night Omen, which causes Phantoms to appear. The higher the level of Bad/Night Omen, the bigger the Phantoms.
Phantoms only attack players with the Night Omen effect.
Phantoms have a chance of dropping bones on top of their standard loot table.
Phantom Membranes can be used to repair any damaged item in the crafting grid.
Ominous Bottles can be found in Dungeon chests.
