So, Ram’s Spring & Dungeon — a charming idle dungeon crawler made by a husband-and-wife team.
I’ve finally reached floor 400, so I figured I’d write down some notes and thoughts along the way.
Hopefully you’ll find them useful!

(This article is translated from Japanese.)

TOC [ close ]

Yep — you’ll definitely want to reroll!

I’m serious, rerolling matters a lot in this game.

Your first big milestone is pulling two ★4+ frontliners (they’ll be your tanks) and one ★4+ healer — ideally, one of them being ★5.
I haven’t reached the endgame yet, so I can’t speak for that part, but at least early on, your tank and healer rarity directly determines how far you can go.

Since Ram’s Spring & Dungeon runs mostly on auto-battle, as long as your healing output > incoming damage, you basically can’t lose.
So if you’ve got sturdy, high-rarity tanks and a strong healer with buffs or AoE recovery, your attackers can honestly be a bit of an afterthought.

On the flip side, if you skimp on raising your tanks and healers, your progress will hit a wall real fast.

Thankfully, you’ll get some free beginner gacha stones from your mailbox (upper-right icon on the main menu).
Use those and roll away!

There’s also a handy “Delete Data” button at the bottom left of the startup screen — meaning you can reroll without reinstalling the app. It only takes about a minute per run.

One exception: if a limited-time character is in the banner, grab them no matter what.
Those units are basically ★6-tier — way stronger than regular ★5s — and can easily become the core of your team.

Recommended Party Setups

The basic rule of thumb for team comp is, from left to right:

Option 1 (strongly recommended):

3 Frontliners
2 Healers
1 Attacker

or, if your gacha luck didn’t cooperate—

Option 2 (backup plan):

2 Frontliners
2 Healers
2 Attackers

Either way, the idea is simple: let your frontliners soak the damage, have your healers keep everyone alive, and let your attackers chip away at the enemy.
Option 1 is by far the most stable setup.

Personally, I had to run with Option 2 for quite a while due to my roster, and… yeah.
My third-position healer kept getting pushed up to the front, got nuked, healing fell behind, the line collapsed, and—boom—expedition failed. Over and over.

So even if your options are limited, a ★3 frontliner is still tougher than a ★4 healer, and might be worth slotting in temporarily just to stabilize your formation.

By the way, each character is either Physical-type or Magical-type, but there’s no elemental or type advantage system like “magic beats golems” or anything like that.
Type differences only start to matter past floor 300, once Artifact bonuses kick in — for example, something like “+8% HP for Magical-type characters.”

That said, you can eventually get all artifacts through persistence, and the buffs apply equally to both Physical and Magical types.
So in practice, there’s no real gameplay difference between them — feel free to build around whoever you like.

Daily To-Do List

First off — don’t forget to grab your free 100 gacha stones from the shop every day. It’s completely free, so take the gift and stash it away!

Next up is Total War (the mode with cumulative damage rankings).
It costs nothing to enter, and rewards you based on your total damage and total healing across all your units.
Early on, you’ll usually get items worth around 60,000 gold per run.
Your total damage adds up over time, and hitting certain milestones gives you even more rewards.
Each run only takes about 30 seconds, so it’s absolutely worth doing daily.

Once material gathering unlocks, tap the material nodes on the map to harvest them.
You can use these materials to upgrade your facilities or sell them for cash.
After you tap a node, you’ll see a timer showing when it’ll be ready to harvest again — use that info to plan your routine efficiently.

First Goal: Reach Floor 100

Your very first milestone in Ram’s Spring & Dungeon should be hitting floor 100.

The game does have idle elements — you’ll eventually earn gold, materials, and EXP automatically — but those systems only unlock once you’ve progressed far enough in the dungeon.
Early on, you’ll make way more progress by actively diving into the dungeon yourself rather than relying on idle rewards.

So yeah — train your team and aim straight for floor 100!

Early Character Growth: Just Focus on Levels

There are tons of upgrade systems — skills, limit breaks, and so on — but for now, don’t overthink it.
At this stage, just keep tapping that “Level Up” button.

Here’s the general priority for stats:

Tanks (except for the ★5 limited Selene):
→ HP = Defense. That’s all you need.

Healers:
→ HP = Defense >> Healing Power.
Crit rate? Don’t bother.

Attackers:
→ HP >> Defense > Attack Power.
Again, crit rate doesn’t matter.

As you can see, HP and Defense are everything.
As long as you don’t die, the auto system will take care of the rest — that’s how Ram’s Spring & Dungeon works.

When leveling your units, tanks come first, then healers, and attackers only get whatever EXP you have left over.
(One exception: the ★5 limited Selene. She’s both the best tank in the game and has attacker-level firepower, so it’s worth boosting her Attack as well.)

Stat-Tuning Guidelines

Frontliners: Boost HP and Defense until incoming damage per hit is about ¼–⅕ of their max HP.
Healers: Raise Healing Power enough to fully restore the frontliners’ damage each cycle.
Everyone else: Upgrade as resources allow — don’t burn yourself out min-maxing.

Once you hit floor 100, you’ll unlock Magic Stones, which means… yep, it’s time for the second gacha phase!

Get Solomon’s Ring — No Matter What

This one’s huge.
You’ll learn about it in the tutorial, but here’s the deal: when you offer Magic Stones to the Spring, you’ll get an Artifact.
If you then press the “Return” button to send that Artifact back into the Spring (it costs 22 gacha stones per Artifact if you have only one artifact), you’ll get your Magic Stones refunded and your total Artifact acquisition count will go down by one.

Now, the more Artifacts you obtain, the higher the cost becomes — both the Magic Stones needed for the next roll and the gacha stone cost for returns.
So yeah, those early Artifacts are incredibly valuable.

And honestly, this is where the game splits into two timelines:
Did you get “Solomon’s Ring” or not?

Solomon’s Ring boosts your Magic Stone acquisition rate — in other words, it makes every future grind more efficient.

If you can grab it early and level it up, that multiplier will snowball fast, letting you build your farming environment much earlier than you otherwise could.

From around floor 300 onward, Artifact upgrades become your main form of power progression, replacing simple level-ups.
So if you slack off here, your progress will start to drag hard later on.

Be patient. Keep rolling. Get that ring. It’s worth it.

Floors 100–200: Facility Upgrades & Strengthening Solomon’s Ring

Once you’ve got Solomon’s Ring, it’s time to push through the dungeon aggressively.

Sure, staying around floor 100 is slightly more efficient for Magic Stone gain (stamina-wise), but honestly… it gets insanely boring. And at that floor, you won’t really be able to level up Solomon’s Ring enough to make a serious impact anyway.

From around floor 100, even just dropping 10 floors noticeably increases your gold income. This is also when facility upgrades start becoming meaningful.
So my advice? Keep pushing down and use the gold you earn to strengthen your facilities.

Magic Stones? Just save them as you go and use them gradually to level up Solomon’s Ring — slow and steady wins the race here.

Facility Upgrade Priority

Most guides mention the same, but here’s the breakdown:

Research Lab >> Dormitory > Bank >>> Unlock New Areas >>> Scarecrow Upgrades >>> Goddess’ Prayer >>>> Training Grounds >>>>>>>>>> Hall of Happiness

Why this order?

Research Lab: The materials you gather automatically here are used for nearly everything — other facility upgrades, unlocking new areas, or selling for a lot of gold. Prioritize this first; it also improves your QoL by letting you progress even when not actively playing.
Dormitory: Increases material yield and improves time efficiency massively. Expensive to upgrade, so it’s best tackled once the Research Lab is fully automated.
Bank: Straight-up the best way to boost gold income. Materials are flexible (used for upgrades or sold), so it’s slightly lower priority than Dormitory but still crucial.
Unlock New Areas: Necessary to significantly boost facility efficiency. Materials from new regions can multiply facility output ~2.5×. Expensive, so placed after the Bank.
Scarecrow: Good experience-to-cost ratio, but expensive relative to the benefit. Tanks often hit practical level caps early, so only invest spare resources here.
Goddess’ Prayer: Upgrade once you have some excess gold/materials. +2 levels = ~1.13× blessing gain per hour. Very cost-effective later, especially when Magic Stone farming becomes a priority.
Training Grounds: Decent efficiency for the first ~2 levels, but beyond that, leveling up here doesn’t matter much until you aim for floor 400. Growth via leveling caps around floor 300 anyway.
Hall of Happiness: Forget about it for now. The main resource it gives (Rikka Orbs) is used to unlock equipment slots, which you likely won’t touch until much later. Early on, all Magic Stones are better spent on Artifacts that benefit your whole party. The yield increase scales per material collected, so upgrading this early gives almost no advantage. Wait until later in the game.

The takeaway: focus on Research Lab → Dormitory → Bank, unlock new areas when you can, then gradually improve other facilities as resources allow.
Magic Stones should be reserved primarily for Solomon’s Ring and other party-wide Artifact upgrades.

Floors 200–300: Adding Skill Upgrades & Limit Breaks

Once you pass floor 200, you’ll start noticing that simple level-ups give diminishing returns.

This is where Skill Upgrades and Limit Breaks start to shine.

Skill Upgrades

Prioritize skill enhancements in this order:

Buffs/Debuffs affecting other characters
Base stat boosts relevant to a character’s role
Damage-increasing skills

A note for tanks (except Selene): their damage output is negligible, so never upgrade their damage skills.

Skill levels 3–4 are enough at this stage.

Costs are very low
Failure rates are minimal
Great cost-performance

After leveling a skill, test it in combat — you’ll notice a clear increase in strength, especially with defensive buffs or base stat boosts.

Limit Breaks

Using the hearts you get from reroll gacha or conversion from gold, you can do 1–2 stages of Limit Breaks early on.

Each Limit Break gives:

+10% Attack
+10% Defense
+10% HP
+10% Critical Damage

That 10% boost is huge in this game — comparable to a Level 4 base stat-up skill.
Early Limit Breaks are cheap and easy, so go ahead and do them — this alone can let you clear 10–20 extra floors compared to unboosted players.

Hearts for Limit Breaks can be acquired from duplicate gacha characters or by converting gold.

Magic Stones? Keep them focused on Solomon’s Ring upgrades.
By this point, all the groundwork you’ve been laying — facility upgrades, leveling, skill boosts, and Limit Breaks — starts really paying off.

Aiming for Floor 400: Artifact Collection & Upgrades

Once you pass floor 300, simple level-based strengthening hits a ceiling.

This is especially obvious for ★4 tanks with low level caps and only HP/Defense as their main stats — by now, both are likely maxed out.

At this point, your only options for further strengthening are Artifacts or Equipment.
Equipment costs an insane amount of Magic Stones, so in practice, Artifacts become your main path forward.

Artifact Upgrade Priority

From here on, Artifacts are the primary way to enhance your characters. Priorities are roughly:

Solomon’s Ring > Enemy Attack Reduction >> Gold Acquisition Boost > Defense Up = HP Up >> Attack Up >>> Others

Why this order?

Solomon’s Ring: Dictates your future farming and progression speed, so max it first. (Level ~11 might be the practical cap for Magic Stone efficiency.)
Enemy Attack Reduction: One of the best “power-up” Artifacts you can get — boosting this makes dungeon progress much smoother.
Gold Acquisition Boost: Not huge, but it noticeably increases income. High-rarity Artifacts, so a nice bonus if you have it.
Defense Up / HP Up: Core Artifacts for making your units tanky. Easy to obtain, easy to upgrade — essential for safely pushing toward floor 400.
Attack Up: Honestly, minor impact compared to the others — can be skipped if necessary.
Other effects: Largely negligible at this stage. They may start to matter deeper in the dungeon, but until then, they’re mostly filler.

The key takeaway: focus on tankiness and utility first, Solomon’s Ring, then gold and attack reduction, and finally any minor buffs.
This approach is the fastest path to reaching floor 400 safely.

Take It Easy

So yeah — that’s a short set of notes on reaching floor 400.

I wrote a lot, but the truth is, this game is truly an idle game. Even if you mess up once or twice, it’ll just take a bit longer — eventually, you’ll get through it.

So sit back, enjoy your carefully leveled-up girls, and progress at your own pace.

I’ve also written a guide for pushing past floor 500, so check that out if you’re curious.
