Death Curse

You point at your target saying "the bells of death will toll for you". A symbol of death appears above their head and they must make a constitution check. If they get lower than 10 a count down will begin, in 3 rounds they will be automatically killed. If it is between 10 and 15, they will have a count down of 2 rounds in which they will take damage equal to half their max hit points. If they get higher than 15 they will be tormented by evil spirits and only receive psychic damage.
