Temporary Hit Points

Certain effects, such as force fields, give you temporary Hit Points. These Hit Points are in addition to your current Hit Points and Stamina Points, and any damage you take is subtracted from your temporary Hit Points first. Any damage in excess of these temporary HP reduces your Stamina Points (and then your actual Hit Points) as normal. If the effect that grants the temporary HP ends or is counteracted, any remaining temporary HP go away.

When temporary Hit Points are lost, they can’t be regained or restored like a character’s normal Hit Points or Stamina Points can be, though some sources of temporary Hit Points have their own rules on how to restore lost temporary Hit Points.
