Is there any way to increase the rank of your current dream eaters?

[Swordsy]

So yeah, the title explains it all. It annoys me how I have some pretty strong B rank dream eaters, each at least level 40, and their entire link board is unlocked, but they really cannot get too much stronger because of lower rank.

For that matter, is there anything I can do about those excess link points? I swear I have a lvl 43 kooma panda with an excess of 900 link points *facepalm*

theres some people saying you can, however the 99% says no you cant increase your dream eaters rank. you can buff their stats with food though, so s ranks are really only necessary if you're a completionist (or if they have better battle abilities with a higher rank)

its also said a higher rank + affinity increases their battle efficiency (attacking and healing more)

the max level you can create a dream eater at is level 65 anyway. (two lvl 99 characters + 58 additional materials)

[Swordsy]

Yeah but I don't feed mine that much because, for me at least, it only increases their stats rarely.

And do dream eaters get different link board abilities with higher ranks?

[Swordsaint]

no. they only gain new link board abilities through disposition unlocks and secret bonus tiles.

by battle abilities i mean the techniques they use in battle. e.g meow wow has horn bounce, horn combo, vanish and such, but i dont know fi rank gives them access to better abilities.
