Have a feeling that this works more like a conventional save point. It won't restore just our points, but everything. So lets not bother with it for now.
Anyway... Hm.
A) If we can, test the scanner on the shopkeeper. Might give some insight to getting a discount, or reveal his secret, evil identity.
B) We should buy at least one tip, I think. Just to see what happens. We can always stash the book in storage if it is actually an item, but I doubt such.
C) I agree with everyone drinking from the fountain and overwriting our save.
D) Lets stash the love letter in storage, because seriously, why are we holding onto it? People didn't like holding onto the headband, but that actually did stuff. This letter does us no good. Also, if/when we play as the recipient of the letter she can pick it up at storage and read it herself.
E) We(Ciro) should carry the spell book because we literally have no way to use our mana. Literally no way. None of our abilities use it beyond the maximum of it.
G) Ask the shopkeeper if we can exchange River Rubies for Fountain Pence.
I'm tempted to say we should sell the short sword and have Riltia use the new swanky sword we got, but that sword would be a real pain to use on this floor. Bah, we have little to sell. The sword is nice, but it would be of more use on other floors due to this one being inhabited primarily with energy beings, from what we've seen... Eh.
H) Sell the shortsword, buy another inventory slot.
Should we do another arena thing?
EDIT: Looking at the save, it just saves our current health. What happens if we do Derm's plan and go over our maximum health? Cancer?
