It's not hacks. Her skill is the same as Wind Weasel, and when fusing same-skill daemons on any other daemon, the skill level can randomly increase.

Fuse enough Wind Weasels on Lilith (Original) and her Phantom Sigh can be maxed to 20.

Lilith (Ultimate) can be maxed the same way, but her skill isn't as readily available as Phantom Sigh.
