Resist Death
( Epic Level Handbook, p. 111)[Epic]
You are capable of withstanding tremendous amounts of damage without risk of instant death.
Prerequisite
Character level or HD 21+,
Benefit
The amount of damage from a single attack that causes you to make a Fortitude save (DC 15) or die doubles (from 50 points to 100 points).
Special
If you are using the Death from Massive Damage Based on Size variant found in Chapter 3 of the Dungeon Master's Guide, this feat doubles the numbers given in Table 3-8: Massive Damage Based on Size. Thus, a Small creature's threshold would go from 40 points to 80, while a Huge creature's threshold would increase from 70 points to 140.
You can gain this feat multiple times. Its effects stack. Remember that two doublings equals a tripling, and so on.
