First aid
From Wormhole Sci-Fi MUD Homepage
This skill is quite useful when your best friend is lying in the dirt,
about to die (incapacitated, mortally wounded). You can try to stop the
bleeding by using first aid.

Please note that to use this skill someone has to be damaged to the point of dying (I think it's 0 to -10 hp or so) without actually being killed, making this skill one that is rarely used. - Ecks
Mobs flagged as 'merciful' would leave you unconscious (I think)... the rest would just hit you again, and kill you. Still, aiding a dying player is worth experience points. At least, it used to be... or was that one of the things that was abused, and had to be switched off? - Artoo
