"MFW Lich is like 'HAAIIII WHATCHA DOOOIN' and I'm like 'IM SLEEPING, LICH, GO AWAY'"- Bob The Necromancer
The Black Lich is one of Bob's minions that appears in the game after the Big Plaque and before the Flying Squid.
He seems to be based on a fictional creature called a Lich. He is wearing an old black cloak, has the ability to float in the air and shoot small green Energy Balls of Doom. The Black Lich also works in the Arcane Laboratory. Hell's brightest mind, the most potent evil wizard the underworld has ever seen, his power is near infinite; but everything comes at a price, tuition in hell is ab-so-lu-te-ly bonkers.
To have access to The Black Lich one needs to have The Big Plague at least at level one.
There is one items in the game that influences the Black Lich's abilities.

Note: Son of the Lich skill does not change other active skills' descriptions but it has, nevertheless, an effect on the active skills. You can activate this skill before or after your other skills - the order of activation does not matter.
