Think i grinded jasmine shards enough so she had 2000 vigor even with the crit items, safe to say she was a monster with pummels (and i forgot to talk about her and coral on the post ops).
As for coral, i will be honest she felt very underwhelming so i didn't use her at all except for the part in the game you are forced to use her (aka the start of world 2), she also consumed way too many items for me to consider her worth bringing.
