Never said it's so unbelievable but I never saw any mention of Seymour being able to summon anything else (IIRC the pilgrimage for the aeons is mainly for bonding with the person who will be then sacrificed to make the final aeon so in case of mother and son that were close it wasn't needed) and I doubt he had any real powers at 10.

And perhaps his mother could've been powerful while still alive for all we know, but if she was sick it's less probable.

One thing that came up in my mind is that since his father Maester Jyscal definitely knew about Yunalesca like the rest of Maesters, he perhaps knew how to get to her easier than through fighting. Of course there is absolutely no evidence on this so it's pure speculation on my part.
