Hunter x Hunter (Gamer System)

Mc dies.
Meets a Goddess with hand fetish, he insults her saying she doesn't have beautiful hands.
Mc gets cursed to only be able to only use his hands to use skills if a skill is used that is not related to his hands, it will receive a debuff of 50% less damage and efficiency. (Movement skills are not affected by this).

The curse, however, was a blessing in disguise
