Kanna's main stat is INT. But HP gives her M.Att, which adds to damage range as well.
Depending on how much INT, %INT, HP, and M.Att you already have, %HP can give you a significant boost.
For real, what am I doing wrong? Is Kanna scaling off HP now instead of int?
Heres the thing as a fellow mage, You have more int in your reinforced but the thing is you gain more from superior as it is the superior and more higher level item. If you had the same stats on the superior as you do the reinforce you gain a lot of damage even hit 1 mil and if you have haku fire with a fan equip on haku that has matt = Magical Attack you have a big damage boost. So I would settle with superior and get 2 pendents sup gollux an earing and keep that ring and you will notice the difference. I can't post mage gear here but yea you maybe get what I mean.
For reference, 27% int and 21% int + 9% hp are roughly equivalent on my Kanna. It will depend on how much base flat hp/mp and %hp you have of course and you seem to have a fair amount of hp at 140k, so I'm not all that surprised that a 33% int ring isn't giving you the kind of gains you might expect over an 18% int ring. You'll probably be best served by saving up and 17 starring your gear. At that point, you'll have enough flat int to notice a bigger difference between the two. Note that an event ring like a SS ring or Cosmos ring will give more range than even a 17* reinforced ring (with a similar potential) due to the large amount of hp Kanna can get from those rings.
Int will win out in the end but don't just reroll a %hp line if you are on a budget.
