Liches

Liches are nasty creatures that are really just more specialized skeletons, with two very distinct kinds existing. The Birkh-type Liches are incredibly frail. They crumble to dust at the slightest bit of light/holy magic and burn like the finest kindling. Birkh-type Liches do, however, have the ability to turn any dead person they touch into a mindless Undead that the Lich can control through telepathy. If the Birkh-type Lich touches a living being, they will implant a curse that will work differently depending on the person. The curse can turn that person into an agent of the Lich, slowly make them mad, or act similar to a disease that slowly turns the skin black outwards from the point of contact, causing necrosis.

The other type of Lich is the Muharib-type Lich. These Liches are the exact opposite of Birkh-type Liches in that they are basically immune to most magic and much stronger than normal skeletons. The downside is that these Liches generally take longer to cast magic properly, and as such makes combat mainly a physical ordeal.
