That is the reason i don't bother with her it has weak stats. You should see wiki first before making decision but you have that far not mlb ing her seems will become waste of an effort.
usually i won't bother to check it 'cause i could get all the events starting medusa to level 100, and i wanted to get rid of all the eidolon R/SR materials.
but still, expected her to have at least more HP or omething..
