Hello, new doktah here, playing because Endfield. currently I'm on Episode 6-16 and still struggling with the stage, but that's not my question for today.

My question is how strong originium arts can be? At first I thought arts was like elemental magic, where they can manipulate fire, ice and so on, but then there are Mephisto's arts that make walking dead (?) or something like that. So I'm wondering, lore-wise, what are the strongest arts out there?
