Prophecy's Mind

Dragon Prophesier (MoE) , Knowledge (arcana) 2 ranks, Speak Language (Draconic),

While psionically focused and in prophetic favor (see Dragon Prophesier), you can lessen the damage dealt by a potentially lethal attack. Any time an attack would reduce your hit points to -10 or fewer, you can expend your psionic focus to instead be reduced to 0 hp. Doing this also ends your prophetic favor. This feat cannot protect you from an effect that slays you without reducing your hit points to -10.

You meld your perception of the draconic Prophecy with a mental focus that provides you with momentary warning when death is at hand.
