The Digivice system in Digimon Up is one of the most important progression features, but it’s also one of the most misunderstood. Many players assume that only equipped Digivices and parts provide bonuses, while others wonder why identical Digivices have different prices despite showing the same passive stats.
The truth is that the Digivice system revolves around stacking passive bonuses through ownership and efficient upgrades. Understanding how it works can significantly increase your Combat Power while helping you spend resources much more efficiently.
This guide explains everything you need to know, including how Digivice passive bonuses stack, the best upgrade strategy, recommended parts for each slot, and which upgrades should be prioritized.
How Digivice Passive Bonuses Work
The most important mechanic to understand is that passive bonuses activate simply by owning a Digivice. You do not need to equip the Digivice for its passive effects to work. Once it is purchased, its stat bonuses are permanently added to your character. For example, purchasing a Digivice grants passive increases such as:
- Attack
- Defense
- HP
If you purchase another Digivice with the same passive bonuses, those stats stack together automatically.
This means every additional Digivice permanently boosts your overall stats, regardless of which one you currently have equipped.
Why Do Digivices Cost Different Amounts?
One of the biggest questions among new players is why some Digivices are much more expensive even though they display identical passive bonuses. The answer is simple: the price reflects progression rather than stronger individual stats.
For example:
- The cheapest Digivices provide your first passive bonus.
- Purchasing multiple inexpensive Digivices lets you quickly stack those bonuses.
- Once you’ve bought all of the cheaper options, the only way to continue increasing passive stats is by purchasing the more expensive Digivices.
In other words, you’re paying for additional layers of permanent stat increases rather than stronger individual items.
Buy Every Digivice You Can
Since passive bonuses stack permanently, purchasing every available Digivice is always beneficial. Rather than selecting only your favorite design or the one you plan to equip, gradually collect every Digivice available. Benefits include:
- Higher Attack
- More Defense
- Increased HP
- Permanent Combat Power growth
Because these bonuses never disappear, every purchase contributes to long-term account progression.
Understanding Digivice Parts
Each Digivice contains several component slots that can be upgraded individually. These include both internal and external parts, each providing two separate types of bonuses:
- Passive Bonuses
- Gear Effects
Although they appear similar, they function very differently.
Passive Bonuses Apply Even Without Equipping Parts
Like Digivices themselves, part upgrades also provide permanent passive bonuses simply by owning them. Even if a part isn’t currently equipped, leveling it still increases your overall Combat Power through passive stat growth. This means upgrading unused parts is never a waste. Every upgraded component contributes toward your total passive bonus value, making your account stronger regardless of your current build.
Why You Should Upgrade Every Part
Instead of focusing all your materials on a single component, it’s generally much more efficient to upgrade every available part evenly.
Reasons include:
- Faster Combat Power growth
- Better resource efficiency
- Higher total passive bonuses
- Lower upgrade costs per stat gained
As upgrade levels increase, costs rise dramatically. Spreading upgrades across multiple parts usually provides much better value than heavily investing into one component early.
Passive Bonuses vs Gear Effects
Many players confuse passive bonuses with gear effects. Here’s the difference.
Passive Bonuses
Passive bonuses:
- Always apply
- Work even if the part isn’t equipped
- Increase Combat Power
- Improve overall account progression
These should always be upgraded across every available part.
Gear Effects
Gear effects only activate when the specific part is equipped.
Examples include:
- Critical Hit Rate
- Skill Damage
- Critical Damage
- Normal Attack Damage
- Resistance Reduction
Unlike passive bonuses, these effects depend entirely on which part you’re currently using.
One interesting exception involves certain button components. Most gear effects remain unchanged after upgrading the part. However, some button gear effects—such as Normal Attack Damage or Skill Damage—increase as the button levels up.
Meanwhile, stronger effects like Critical Hit Rate generally remain fixed regardless of upgrade level. Because of this, button upgrades can offer slightly more value than other components once your passive upgrades are well balanced.
Best Digivice Parts to Equip
Choosing the right gear effects is just as important as increasing passive bonuses. Below are the recommended parts for each slot.
- LCD Slot Equip the Green LCD. Its Critical Hit Rate bonus is considered one of the strongest offensive stats available, making it the best overall choice for most builds.
- Button Slot Use the Blue Button. Its Skill Damage bonus provides consistent damage improvements and also benefits from level scaling, making it an excellent long-term investment.
- Body Slot Equip the Blue Body. Its gear effect lowers enemy Critical Damage Resistance, allowing your attacks to deal significantly more damage during combat.
- Memory Slot Choose the High Capacity Memory. Its Critical Damage bonus offers one of the highest damage increases among all available Memory options, making it the preferred choice for most players.
- Debuff Slot This slot is less straightforward because each option weakens enemies differently. Available effects include: Damage Down, Normal Attack Damage Down, Combo Damage Down! The strongest option depends on your opponent and game mode. For general use, Overall Damage Down appears to be the safest choice, although further testing may reveal stronger situational options.
- Enhancement Disc Slot Equip the Critical Enhancement Disc. Its Critical Damage increase provides one of the strongest offensive gear effects available and fits nearly every damage-focused build.
Spend Digi Chips Carefully
Digi Chips are one of the game’s most valuable currencies.
They are required for:
- Obtaining new Digivice parts
- Upgrading existing parts
Since supplies are limited, avoid heavily over-investing into a single component too early.
Instead:
- Unlock more parts first.
- Upgrade everything evenly.
- Focus on passive bonuses.
- Invest deeper into important button upgrades later.
This approach gives the highest overall return while conserving valuable resources.
Best Digivice Progression Strategy
If you’re unsure how to progress efficiently, follow this order:
- Purchase every available Digivice, starting with the cheapest options.
- Continue buying more expensive Digivices as they unlock.
- Upgrade every Digivice part evenly for maximum passive bonuses.
- Equip the strongest gear effects for each slot.
- Save Digi Chips for unlocking new parts before heavily upgrading existing ones.
- Invest additional levels into powerful button components once your passive bonuses are well developed.
Following this strategy provides consistent Combat Power growth while keeping upgrade costs under control.
The Digivice system in Digimon Up is designed around permanent progression rather than temporary equipment. Every Digivice you own and every part you level contributes to your character’s passive stats, even if those items are never equipped. By collecting every Digivice, upgrading all parts evenly, and selecting the best gear effects for each slot, you’ll build a stronger account with far greater long-term efficiency than players who focus only on their active equipment.
