Well, if they buy HT 14, they probably will survive it. Aren't the PCs supposed to be vampires?!

I think you're not paying attention to some of the basic mechanics of GURPS. The probability of surviving any death check with HT 14 is better than 90%.

Every +1 to HP adds 6 injury to your life expectancy - just less than 2d injury. A character with 10 HP is automatically dead at -50 HP (60 HP possible life expectancy). A character with 11 HP is auto-dead at -55 (66 HP possible life expectancy). And so on.

If you have just a few extra HP and just a couple points of added HT, you're already extraordinarily tough.....

EDIT: An average, zero point NPC, with 10 HP, is only automatically killed with an average of about 17 dice of injury....
