The most common way that your character gets hurt is to take lethal damage
and lose hit points
What Hit Points Represent: Hit points
mean two things in the game world: the ability
to take physical punishment and keep going, and the ability
to turn a serious blow into a less serious one.
Effects of Hit Point Damage: Damage
doesn't slow you down until your current hit points
reach 0 or lower. At 0 hit points
, you're disabled.
At -10 or lower, you're dead.
If you ever sustain a single attack deals 50 points of damage
or more and it doesn't kill you outright, you must make a DC 15 Fortitude save. If this saving throw
fails, you die regardless of your current hit points
. If you take 50 points of damage
or more from multiple attacks, no one of which dealt 50 or more points of damage
itself, the massive damage
rule does not apply.
