Ddraig said that Gressil could developp a resistance to Penetrate if Issei uses too much against him, reflection and divide are useless against Gressil since he is a power type who mainly uses his fist, he didn't have difficulties against Issei in CxC whereas he was holding back and Issei said that without P DxD G, he can't beat him.
