If you’ve just unlocked Crests in Digimon UP, you’re probably wondering whether they’re worth investing in straight away. At first glance, the system looks simple—collect fragments, summon pieces, and fuse them together—but once you start digging into it, there are quite a few mechanics that aren’t explained very well.
I spent some time looking through every part of the feature, and honestly, there are a few mistakes that are really easy to make. Spending too many Emeralds on Crest summons or upgrading the wrong pieces too early can slow your overall progression.
So, if you’re about to unlock Crests or you’ve just gained access to them, here’s everything you need to know.
Digimon UP GR Crests Guide: How to Unlock, Farm Lost Sector, Fuse Crests & Upgrade the Right Way
The Crest system becomes available once you meet both of these requirements:
- Reach Server Day 12
- Clear Stage 500
Once both conditions are met, the Crest menu unlocks and you’ll also receive your first free Crest piece.
Each Crest is made from multiple fragments that eventually combine into a complete Crest.
Where to Get Crest Pieces
There are several different ways to collect Crest fragments.
Lost Sector Tower
This is your main farming location.
Lost Sector rewards Crest materials after every successful clear.
Unlike many game modes, there aren’t daily tickets limiting your attempts.
Instead:
- Progress as far as your team can.
- You cannot repeatedly farm lower stages.
- The only way forward is by becoming stronger.
Because of this, Lost Sector gradually becomes one of your long-term progression systems.
Crest Summons
You can also obtain Crest fragments through the Crest Summon banner.
Each summon costs resources, but this shouldn’t be your first priority if you’re still developing your account.
More on that later.
D1 Grand Prix Shop
One of the most important sources is the D1 Grand Prix Shop.
This is especially important because UR Right Tablet Fragments can only be purchased here.
If you’ve been ignoring PvP, now is a good time to start participating consistently.
Lost Sector Explained
You’ll probably expect Lost Sector to appear alongside the other dungeon activities.
It doesn’t.
Instead, you’ll need to manually enter the Lost Sector from its own menu, which can be slightly confusing the first time.
As you progress through sectors, enemies become noticeably stronger.
Later sectors are surprisingly difficult, even for players with high combat power.
One useful thing to know is that Lost Sector doesn’t use stamina or tickets.
Your only limitation is your team’s strength.
Should You Upgrade Crests Immediately?
This is one of the biggest questions players have.
At first, upgrading a Crest doesn’t appear to unlock anything exciting.
You’ll gain basic stat increases like HP, but additional effects don’t immediately appear.
It’s possible these extra effects unlock at higher enhancement levels or after reaching a higher rarity.
Since the system doesn’t clearly explain this, it’s better to avoid spending all your enhancement materials immediately.
Waiting until you’ve built stronger Crests is generally the safer approach.
Crest Summon Rates
If you’re thinking about spending lots of Emeralds on Crest Summons, you may want to slow down first.
The summon rates for high-rarity Crests are extremely low.
Fortunately, there is a pity system.
After:
50 Crest Summons
you’re guaranteed a UR Crest Shard or better.
Without pity, however, naturally pulling UR fragments is exceptionally rare.
Should You Spend Emeralds on Crest Summons?
For most players, the answer is not yet.
Your Emeralds are generally better spent elsewhere, especially if you’re still progressing through the early and mid-game.
The biggest account-wide power boosts still come from improving your Tamer Rank rather than chasing Crest fragments.
Until your Tamer progression slows down, Crest Summons shouldn’t be your main priority.
Don’t Ignore Tamer Rank
Even after Crests unlock, Tamer Rank continues to provide some of the largest combat power increases in the game.
For reference:
- Rank 12 → 13 requires 7,000 materials.
- Rank 14 → 15 requires 15,000 materials.
These upgrades provide far more combat power than most early Crest upgrades.
If you’re managing your resources carefully, prioritising Tamer progression is usually the better investment.
How to Get GR Crests
GR Crests require combining two matching Crest fragments.
Each Crest consists of:
- Side A
- Side B
Once both matching pieces are obtained, they can be fused together into a complete GR Crest.
The problem is that obtaining both halves takes time.
One side mainly comes from Crest Summons.
The other side is primarily obtained through the D1 Grand Prix Shop.
Since PvP currency is earned fairly slowly, completing a GR Crest is definitely a long-term goal rather than something you’ll finish in a few days.
D1 Grand Prix Shop Tips
The D1 Shop sells valuable Crest fragments, but they aren’t cheap.
Each fragment costs a significant amount of PvP currency.
Even active players won’t buy these very frequently because daily earnings are fairly limited.
To maximise your progress:
- Complete PvP battles regularly.
- Use refreshed battle attempts whenever available.
- Save your currency instead of spending it on less valuable items.
Consistency matters much more than rushing.
Can You Use Every UR Crest Immediately?
Not always.
One interesting thing about the Crest system is that you can obtain UR fragments long before they’re actually usable.
For example, some UR Crests require clearing much higher Lost Sector floors before they can even be equipped.
So don’t panic if you summon a powerful UR and can’t use it immediately.
Just keep progressing through Lost Sector.
Should You Level Up Crests Before Fusion?
This is another area where it’s worth being patient.
At the moment, it’s unclear whether enhancement levels carry over after fusion.
If levels reset during the fusion process, upgrading temporary Crest fragments would waste valuable materials.
Because of that uncertainty, a safer strategy is:
- Keep useful UR fragments.
- Wait until you complete the full GR Crest.
- Invest enhancement resources into the final version instead.
Unless future updates confirm that enhancement levels transfer, this approach minimises wasted resources.
Recommended Farming Priorities
If you’re wondering where your daily effort should go after unlocking Crests, this order works well:
- Continue improving your Tamer Rank.
- Push Lost Sector as far as possible.
- Complete D1 Grand Prix battles every day.
- Save PvP currency for UR Crest fragments.
- Avoid overspending Emeralds on Crest Summons.
- Upgrade finished GR Crests instead of temporary fragments.
Following this order helps your account grow steadily without wasting valuable materials.
Best Build Considerations
While building around Crests, your overall character build still matters more than individual Crest bonuses.
One effective approach focuses on:
- Evasion
- Critical Rate
This combination works particularly well for offensive Digimon like WarGreymon, improving boss damage while also helping clear normal enemies more efficiently.
Instead of spreading your stats across multiple mechanics like stun, recovery, evasion and crit all at once, specialising in one clear build often produces better overall results.
Digimon UP Crest Guide Summary
Here’s a quick overview of everything covered:
- Unlock Crests after Server Day 12 and Stage 500.
- Farm Crest fragments in Lost Sector.
- Collect additional fragments through Crest Summons.
- Buy UR tablet fragments from the D1 Grand Prix Shop.
- GR Crests require both Side A and Side B fragments.
- Don’t rush Crest upgrades before understanding fusion inheritance.
- Prioritise Tamer Rank over Crest Summons for better power gains.
- Complete PvP regularly to earn Grand Prix currency.
- Push Lost Sector whenever your team becomes stronger.
- Save enhancement materials for long-term GR Crests whenever possible.
The Crest system adds another layer of progression, but it’s definitely designed as a marathon rather than a sprint. Lost Sector, PvP, Crest Summons, and fusion all work together, so trying to max everything immediately isn’t realistic for most players. The biggest mistake new players make is treating Crests like an urgent power spike when they’re really a long-term investment.
For now, focus on pushing Lost Sector, staying active in the D1 Grand Prix, and continuing to level your Tamer Rank. By the time you’ve collected both halves of a GR Crest, you’ll have saved enough resources to upgrade it properly instead of wasting materials on fragments you’ll eventually replace.
