[Spiteful] - You may prevent a player from winning any item from dates, provided that you yourself have not been invited.
that sounds like scum valentine ability, why? because so far every single town valentine is a boost for yourself:
cal - after you find soulmate, you earn twice as much money
indigo - after you find soulmate, you gain extra items
am - take 3 out of 5 coins lead is paying for yourself (how i read it)
hime - nerfed in dates but her items work better
now scum:
Kiku - steals items from other date
now why your ability hurt other people instead of boosting you?
