A Spirit user must charm a stake with Spirit, it must be a Spirit user who can charm objects. Then once they have the Strigoi they want to come back to their original state, close enough to them, the Spirit user must stake the strigoi in the 심장 with the 참드 stake.
당신 stab the strigoi in the 심장 with a spirit stake! Like Lissa will put spirit into it and use it on them, Only the spirit use's can bring them back to the old way.
