The Bathhouse Opens for Business

After “saving the master”, regardless of the outcome, talk to Snow, who is finally convinced it’s time to open the bathhouse in the back of the tavern again, but some work is needed before we can...make good use of its services~. Ebb and Flo, or Witer (depending on how you completed “saving the master”) will take care of the hard work itself, your job, this time, is just to collect 20 sauna rocks (literally just normal rocks) and bring them to Ebb, on the side of the tavern, or Witer, inside the tavern.
Rocks are collected from ghosts at night or by exploring around, but the deed is much faster if you explore the lake, so no enemies can bother you.
The reward is 400 coins, other than being able to use the bathhouse’s facilities whenever you want, obviously, starting from the following day.
Taking a bath alone costs 100 coins (but the first bath is free), while inviting a guest costs 200 coins; regardless, taking a bath while Ebb is at the counter heals you and sets your HP to x1,8 their max value, while taking a bath with Flo there has the same effect, but for MP.
See who you can invite and when in the extra section (“bathhouse guests”).
Since 0.27, Chet is going to sell an incense burner and incense after this quest: it costs 2000 for each charge, but it allows you to re-stat in your room at any time!
