Elf — Bottomless Well
The first time each day an elf would be energy drained, they are instead not energy drained. After the first time, the number of negative levels applied is reduced by one (minimum 0).
In addition, when they are the victim of ability drain, a number of points of ability drain equal to half their level is converted into ability damage instead.
Every night, an Elf picks a number of creatures equal to her Charisma modifier (minimum 1). These creatures, if within 30 ft. of her, automatically stabilize while Dying.
