Mermaid’s Sanctuary - 1F Treasures¶
| Treasure | Location |
|---|---|
| 633 gold | In a chest to the southwest of the northern entrance. |
 Bronze Knife |
In a pot northeast of the western stairs. |
| Holy Water | In a pot northeast of the western stairs. |
 Angel Bell |
In a chest south of the western stairs. |
Depending on how you entered this area you can appear in a few spots, but if you use Zoom to return here after your first entrance the game will put you on the northern edge of the map, so we’ll start from there… plus we kind of want to start at 12:00 and work our way counterclockwise to the stairs down on the eastern edge of the level… with a stop along the way to get some otherwise inaccessible treasures.
From the northern entrance head southeast past some stairs down and loot a chest to score 633 gold, then start working your way counterclockwise until you find some stairs down along the western edge of the level. Go down these stairs to reach the western part of the B1 level, which is isolated from the rest of the dungeon. We’ve got some treasures to get that’ll take us down to B3, but we can’t get them by going any other route, but a detour now will save us some cleanup later.
When you reach B1, note some stairs immediately south that’ll lead down to B2. Ignore them for a moment, circle north, west and south around the stairs and when you reach a fork head east to find 30 gold in a pot. They can’t all be winners… Backtrack to the stairs and head down to B2, then head north and east to find a pot near a coral formation containing a 
Necklace of Immunity. To the west you’ll find stairs down, but ignore them for now and continue west to find an area exit to find an underwater chamber, a separate B2 map. Search a pot near a counter to find some Dragon Scales, then find another pot in the western edge of the chamber near some stairs, inside of which was 2x Magic Phials. Backtrack to the main part of B2, go down the stairs you neglected earlier to reach B3. Head south to find a chest and loot it to open Full Plate Armour.
Now that this diversion is over with, work your way back up to 1F and from the stairs leading down to B1 head northeast to find two pots. In the right pot you’ll find a Bronze Knife and in the left pot you’ll find Holy Water. Now head south, go up a ramp to the southeast, and when you reach a fork turn west to find an Angel Bell in a chest. You’re pretty much done in this area, but press on east and north to find some stairs leading down to B1.
Mermaid’s Sanctuary - B1 Treasures¶
| Treasure | Location |
|---|---|
| 30 gold | On the isolated western part of the level, southeast of the stairs. Found during an earlier diversion. |
| Full Moon Ring | in a chest north of the easternmost stairs. |
 Oomph Powder |
In the northern cave, near some bright green collar - this is a hidden item. |
 Battle Fork |
In a chest southwest of the southeastern stairs, along the southern part of the level. Can only be reached by going upstairs from B2. |
| Magic Water | In a pot along the western edge of the southern part of the level. Can only be reached by going upstairs from B2. |
From the stairs along the eastern edge of the level, head north and when you find a fork, hang northeast to find a chest containing a Full Moon Ring. Backtrack to the fork, then head northwest and north to enter a cave. When you reach another fork, head west and search near bright green coral to find Oomph Powder on the ground - this is a hidden item. Continue northwest, west, then south to exit the cave along the northern part of the level and note some stairs to the southwest - the lead back up to 1F, and just like we ignored them before, we’re gonna ignore them again, instead opting to continue west to another flight of stairs which will take us down to B2.
There’s more treasure to be found on B1, which is noted in the item box above, but we can only reach them from B2 (B3, actually!), so don’t fret over Nose for Treasure telling you you’re not down - we’re aware, we’ll get it done.
Mermaid’s Sanctuary - B2 Treasures¶
| Treasure | Location |
|---|---|
| Dragon Scale | After exiting B2 via the western exit you’ll find yourself in a separate chamber. Search a pot near a counter to find this. Found during an earlier diversion. |
| Magic Water x2 | After exiting B2 via the western exit you’ll find yourself in a separate chamber. Search a pot near the stairs to the west to find these. Found during an earlier diversion. |
 Butterfly Baton |
In a chest northwest of the northernmost stairs. |
| 348 gold | In a pot in a side-chamber you can reach by exiting B2 to the north. |
| 18 gold | In a pot south of some stairs that connect B3 to B2, in the eastern segment of the level. |
 Enchanted Robes |
In a chest in a side chamber you can reach by exiting B2 to the east. |
Alrighty! Back to B2! This level is even more fragmented than the previous ones, with discrete sections to the west (which we already explored), south, east and northwest (where we’re currently at). Needless to say, there’s no straight-forward way to explore that doesn’t involve dipping into and out of other levels, but we’ll manage!
Follow the northern wall northeast until you find a chest containing a Butterfly Baton, then continue east to find an exit to the north and stairs down to the south. Exit north first to find yourself in another side-chamber, and explore to the east to find a pot containing 348 gold. Return back south to the main level and take the stairs down to B3.
Our current stay in B3 will be brief - everything to the west of the stairs you entered from is empty space, so ignore it and from the stairs head east, north, then east again and when the path splits, go south instead of southeast and search the ground to the left the the end of this short area to find an Angel Bell on the ground, another hidden item. Backtrack north, then go southeast, then south to find some stairs leading back up to B2.
On B1, go down the northwestern stairs and press on until you encounter a pair of Octopests - the dungeon’s first minibosses!
Focus on one at a time, as once their health is low they’ll start getting two attacks per turn - you don’t want to see 3-4 breath attacks coming your way!
Back on B2, search a pot immediately to the south of the stairs to find 18 gold, then head north to encounter your first miniboss of this dungeon. Or rather, minibosses - you’ll be facing a pair of 
Octopest enemies, powerful octopus-like enemies who can hit hard in melee and deal heavy damage to the entire party with their icy breath. Protect yourself again ice ahead of time and be ready to spam 
Multiheal, if you have it. They’re weak to lightning, so use spells like Zapple and abilities like 
Lightning Slash to deal extra damage to them. Focus on one enemy at a time, however, as they start getting double attacks when their health is low, and taking four ice breaths in a turn is very difficult to survive for long!
Once the Octopests are dead you’ll chat with some Mermaids before you’re free to explore… but there are no more treasures on this map! Yeah, B2 wasn’t all that compelling, loot-wise, but there is technically one more item you can get. Exit to the east to find a side chamber, then continue east and loot a chest to score some Enchanted Robes.
Return to the main part of B2 and note some stairs down to B3 near (east of) the ones that took you to this section of B2. These lead down to an isolated part of B3, and there is a treasure here, but you can’t reach it during your first visit to this area, so ignore these stairs and head south to find some stairs up, instead. These will take you back to B1, specifically to the southern section of B1 we couldn’t reach earlier.
When you surface at some stairs along the eastern edge of B1, head southwest to find a chest containing a Battle Fork. Now make your way around to the west to find more stairs going down, which will take you to the southern section of B2 - we’ll get there shortly, but first let’s finally finish up B1. Head to the western edge of this segment of the level and loot a pot to score another Magic Water. Once done, take the stairs down to B2.
You can punish the Yellowfink minibosses with powerful spells like Kacrackle or Kaswoosh!
But don’t take them for granted, as they can deal heavy damage with their All Out Assaults!
Make your way east and north from the stairs to find this dungeon’s second miniboss encounter, this time with three 
Yellowfink enemies. These are actually easier than the Octopests, but they can be dangerous - their “All Out Attack” can deal massive damage (100+), and if they all decide to, say, target Matilda or Peronel, there’s a good chance they won’t have the HP to survive. RNG gonna RNG, so just hope for the best and keep healed. On the plus side, the Yellowfinks are weak to ice and wind, so use Matilda’s Kacrack/
Kacrackle and/or Peronel’s 
Swoosh/
Kaswoosh to deal heavy damage and win the damage race against these foes. Once one falls the fight becomes easier.
After the fight, talk to some more mermaids, then head down some stairs to the west to reach a new part of B3.
(1 of 3) In the depths of the Mermaid’s Sanctuary you’ll run afoul of the Toadalitarian and its minions, who can attack and buff!
Mermaid’s Sanctuary - B3 Treasures¶
| Treasure | Location |
|---|---|
| Full Plate Armour | Go down a series of stairs along the western edge of the area to reach B3, then loot a chest to the south. Found during an earlier diversion. |
| Angel Bell |
Go down a series of stairs along the northern segment of the level until you reach B3, then head northeast to reach a fork. Head south and search the left side of the area to find this. It is a hidden item. Found during an earlier diversion. |
| Sage’s Elixir | Along the southeastern edge of the southern segment of the level, in a chest. |
We’ve already explored most of B3 by now, and obtained two of its four treasures. You can’t get one, so this will be pretty quick - head east past some stairs leading down to B4 and loot a chest to obtain a Sage’s Elixir. Nice. Take the stairs down to B4 and with that you’re pretty much done with the treasure in this area, save for one item you can only get later. Just head north through B4 to finally find the leader of the fiends that desecrated this sanctuary. Defeat the 
Toadalitarian boss and its Woman o’ War harem to complete this dungeon.
