Comprised of the spirits of 108 drowned women, Milotomb uses its alluring movements to draw men to the same fate. It is more popular with feminine trainers than it is with masculine trainers.

There's a soul trapped in each of the 108 crystal shards that make up Diantomb. If it likes its trainer enough, Diantomb will discard its oldest soul and replace it with its Trainer's.
