Ray didn't excel in practicing magic spells, as he could only cast a few. In fact he was just as capable of a bard in this regard. However, he was really good at recognizing certain spells, so he immediately saw what was really going on. Joseph had realized that he could not win, so he made his final move by burning himself and summoning the power of the God.
This spell was just a different kind of God Descending Spell and would have a better result compared to the one cast by Sean. This spell may cost more, which meant that every time this spell was practiced, a powerful and faithful follower would be the sacrifice.
