What the Matrix Walker said - if it's a NPC, this is just how it works. If it's for a PC, it's trickier, but I think it can be done. The end goal here is to basically make their Will = their HP. I'd first start with
Modifying Other Characteristics (
GURPS Power-Ups 4: Enhancements, p. 10). Substituting ST for another attribute is not currently legal - but you can sub a specific aspect of ST (I did this in
Pyramid #3/69: Psionics II in my article "Mind and Body" where the higher of ST or Will determined the basic damage of a psi-sword; see p. 18 of that issue for all the gory details). In this instance I would use the rules for
Modifying Other Characteristics and add "Based on ST, HP Variant, +20%" directly to Will. HP wouldn't be used at all unless the critter would somehow become a physical being and HP would equal Will, though a cost of 1 points per level of Will would be needed in the form of a new advantage. So if the
gaster had a Will of 11, he'd need to pay 11 points to use his Will instead of his HP for damage purposes. The GM would need to be careful though as this might led to some unpleasantness for playing characters with this trait as they take HP damage they become increasingly susceptible to supernatural powers that are resisted by Will!
