Whenever a PC drops to 0 HP from damage, a roll is made on a table for that damage type (e.g. "Lingering Injuries - Fire"). The selected injury details are added into the PC's Notes, and a mostly-automated effect is added on the combat tracker.

Some injuries can be healed my magical healing; this is also mostly automated.
