@Hockeystarlet How did you get it because the mystical blessing is not free money if you got it from a tomb it will eventually fade to zero if you go * from a relic it will eventually fade, keep in mind the mystical blessing is not free money because you had to work hard to find that relic.
@cocohorselover Hi, I haven't played that family in a while, but if you want get rid of it use the relic on another person outside the household, they won't get the money, because NPC sims are too stupid to realize they got a blessing and get money, but the blessing will be removed from your sim.
