Request: Lich Template Class

[Necrosnoop110]

Would someone mind creating a Lich Template for 5th edition? Basically the 5th edition version of the 3.5 Lich Savage Progression (http://archive.wizards.com/default.asp?x=dnd/sp/20031212a). With the intention of 4 (or more) levels that a PC could multiclass into. Looking to keep this within 5E's gentler power curve so if it would be a slower progression (i.e., take more levels than 4) or if it pushed some stronger abilities out of the range of 20th level, that's fine to.

Thanks,
Necro
