Sense is "go for it" but with a lot of "that's not a human, that's an elemental magic supercomputer, technically" details. Power level high but specifically a step down from "godly."

Also I have no idea if Ryo's "healers can sense other healers" bit applies to other kinds of magical healing, but if it does, it'll ping on Asch (in weird like... doublevision ways) since being a healing blade is inherent rather than learned.
