ToME: the Tales of Maj'Eyal

On my most recent necromancer playthrough Celia dropped two hearts upon death. She hasn't done this when I've killed her previously and I couldn't reproduce on a restored save. Only thing unique this time was she was invisible and standing in one of her ghoul's retch areas. I couldn't tell what killed her as she had a ton of negative effects on her at the time doing damage and the log didn't list the killing hit. A darkness pulse from getting a soul was the last log before the quest completed.

Both hearts show in inventory and work independently.
