Thanks for the reply RangerWickett.
Primitive Screwhead: I'm not quite ready to allow my player to become a lich (even a limited version). While I haven't fully stated it out I was thinking something along the lines of an item that allowed you to temporarily take on features of the undead. In my thoughts the item would have 6 charges each day (renewed at midnight) To consume a charge, and activate the item, you need to take a bite our of the cheese. So long as one charge remains the cheese reforms at midnight as its charges replenish. If all the charges are gone then you have eaten all the cheese and can no longer make use of its power. In all cases the effects would only last a few rounds to a couple minutes.
I haven't fully decided how I would want to handle the transformation but my current thoughts are as follows:
1) You adopt a new template based on how many charges you consume. 1 charge would be the skeleton or zombie template, three charges would be a lich or ghost and all five would grant you the abilities of a vampire. Going beyond the
SRD could of course open up options like a death knight, shadow, or other sorts of undead.
2) Instead of granting a template to be added onto a character consuming charges could instead grant abilities of the undead. Such a case would look something like this, and the effects of lower charges would be cumulative with higher ones:
1 = Undead subtype
2 = Resistances/Immunities to energy types or Damage Reduction (I'd probably give an array to choose from to represent the different types of undead out there)
3 = Fast healing
4 = Minor ability (I'd create a list to choose from that draws from abilities possessed by undead)
5 = Major ability (same as above but better).
3) This is much like number 2 but organized quite differently. Instead of a set list based on how many charges you use I'd make just a general list of powers to choose from like; Fast Healing, Energy resistance, Special ability, Damage reduction (and probably one or two more).
Each time you use a charge you would be able to select an ability and the amount of charges would determine its strength. For example, if I consumed one charge I could gain resistance to fire equal to 5. However, if I expended three charges I could gain resistance to fire 15, fast healing 3, and one special ability (which would be chosen from a tiered list to accommodate different charge values).
