hey there
I was thinking it would be a great addition to make touchstones rechargeable using souls and meat in order to extend the life of the touch stone (maybe make it so the pig heads are fixed and get dead face on them) with a maximum of 4 charges. the player would then have to recharge the touchstone each time in order to add another life (with a maximum of 4 charges)
and resurrecting at a gravestone as a zombie would be cool
