Also I get that you're trying to balance things out, but there has been no canonical indication that the Golden Fleece can lose its power (and, if I recall, Leo might have said that the healing power was a later/film addition and is not canonical to the original myth). If you want to give Arthur a comparable healing artifact, maybe you could use the Holy Grail or something.

Either way I strongly suggest clearing up which version of Jason you're using and also specifying which Argonauts and which knights will be present.
