Yeah, it's simple, but it doesn't work.The librarian with the high WIL save will stand before a foe that sends the barbarian with the low WIL save running.
Doesn't solve anything -- you still need rules for what those DCs are. I'll admit that it means not adding another subsystem, but it doesn't remove the need for work to be done. Unless you want to handwave the DCs, which I don't, and is why I posted this thread in the first place.
I keep returning to the idea of zombies taking "critical hits" when they "should" die -- but they keep coming, minus an arm, or while advancing up the shaft of the spear, etc.Some enemies will fight to the death. The horde of zombies will keep coming until the PCs have defeated it; the construct guarding the crypt will not stop until it is a pile of rubble.
If we take this outside our gaming experience, and we totally remove the expectation of a fight to the death, it's not clear that the orcs even attack in the first place. What do they think they're going to get out of it? And who wants to be the first orc to charge the great elf champion with the glowing sword?There are four times as many orcs as PCs. At what point are they going to realize they're dropping like flies and their numbers are *not* an advantage this time?
Boom. All done. Simple morale system, using the existing rules.
All right, you've managed to persuade me.
I'd probably tinker with it to make it less simple -- this IS D&D, and who wants simple D&D rules?
