Okay, I think I'd already mentioned that I prefer to use this alternative rule for massive damage:
So for Angus, the threshold would be 60, but for the halfling Gala of Inanna, Elle, the threshold would be 40. For Screech and Phar's familiar, it would be 30.
But I also don't like the whole save or die option, so I'm going to say we use this variant rule as well:
That, for me, seems more fair and still could lead to character's dying, if the other PCs can't stabilize them in time.
Thoughts?
BTW, I think I'm going to house rule the Death Domain's Death Touch to use these rules, as well. I have to think about how I'd rework the domain. It wouldn't be exactly the same.
