Are there certain items you can't send to your mysterious melody partner? I've tried to send them two different types of potions but neither one showed up in the list. Is it set so only items under a certain rarity can be sent?

There is no limit on the things you can send your MM (other than stuff locked to your account like giftboxes and loyalty totems). Are you sure you didn't have too many items in your inventory?

I have 85 items. Is that too many to show for MM?

Did you scroll all the way down on the pull-down menu?

Yeah, i went through it a few times to make sure i hadn't just skipped over it

You can have up to 100 items in your inventory, maybe try clearing it except for the potion? Sounds pretty strange

It showed up now. Guess 85 WAS too many items

Yay! I'm glad it showed up after all!

Lock please?
