There is yup! The Minotaur has 3 phases. When he enters his 2nd phase, his attacks (above his head) will be replaced with a Charging icon, you need to make him orgasm within 3 turns otherwise he will unleash that attack. Orgasm's sensitive stuns him. If he enters a new phase while already sensitive, in the current version the charging timer will pause until his sensitive ends.
Good luck!
