While Raze was in the middle of fighting against the two warriors, he had thought about using more of his magic skills. Using magic along with the Demonic techniques allowed it to be more effective, but things like Dark Pulse would surely take them by surprise.
When thinking about magic, though, it made him think about something else that he could use. Something that took little magic to activate and would be incredibly strong. In a situation like he was in, did he care about Alter's rules? Of course not.
If he was dead anyway, then what use would it be to follow Alter's rules to survive? After pushing the two away, one with his swordsmanship and the other with his wind magic, Raze had the time to summon his statue. With it in his hand, he used Dark magic, and dropping it to the ground, it started to grow.
