Well, one of my gaming group is utterly hellbent on running a game of BESM d20, and has already ok'ed my idea to play a lich as my character. It is a game using the corebook only, level 10, with 50 initial free character points, using the Dynamic Sorcery attribute for magic. Unfortunately for me, what I know about making good characters in BESM d20 could fill a thimble halfway, so I am basically lost. How would I go about making a badass lich in this system with these given rules?
