Before heading out, he went to check out the [Potions] tab, too.
He hadn't paid much attention to it before because he was cozy in his inn.
If he got tired or a bit injured, he could literally just enter his room, lay down anywhere, and he'd practically be in a healing pod.
In those times, he particularly loved being the Innkeeper.
Too bad he hadn't had many customers yet— I.e. more than one—to appreciate its greatness with him.
Not to mention, those potions were…one-time consumables, and he had to pay the minimum of 1 gold, which was not cheap. Since he hadn't needed them, he simply didn't bother before.
Anyway, for potions, it was interesting. There were fixed options at the top, while the other three were rotated and changed daily, like many other items.
