Gem of Souls only copies the descriptions of the innate abilities, which is a problem when the gender of the one who gained the ability differs from the one he defeated.
Cornelius Constantine with Gem of Souls defeats Rumiko - has innate ability "...when she switches out."
Heh, I got about 17000 points now, first try... you just have to hit them immediately after they spawn.
However, I won't be playing this game again now that I have them.
