Additional stuff to add I guess. Honestly if you have enough jewels, I'd wait for another 3k roll if it fits nicely within the time frame of 2 weeks.
Snow Raphael not impacting the team... is not true IMO. Providing B frame debuff relieves you of the necessity of running D'Art without sacrificing 50% def break. While Belphegor does cover that pretty well, I'd take an extra orb removal gladly, as well as 2 turn 30% dmg mitigation, which just so happens to stack with Joan. Defensively, Snow Raphael kind of trashes Belphegor. That does give you the issue of damage, but the light and water teams look very defensive already anyway. I'm not discounting L Tsuku tho, but tbh I would be as equally torn in this situation.
