Dungeon Modifiers: An overview

Development Update

This is an exhaustive list of Dungeon Modifiers released on version 2.0.2

What is a Dungeon Modifier?

A Dungeon Modifier (“Dungeon Mod” or just “Mod” for short) is a concept you might be familiar with if you play RPGs assiduously. 

In short, a Dungeon Mod is a “rule” that alters how a particular dungeon is played. This means that you can see the same dungeon but with different Dungeon Mods! 

There are also different variants of Dungeon Mods, each with a certain level of “intensity”, that will either increase your reward (or risk!) or lower it.

Needless to say, there are a lot of Dungeon Mods. We are releasing our first batch, mostly centered on different aspects of dungeons, like altering how strong the enemies inside are, or how rewarding the dungeons are. In the future, we want to expand on this system which opens unique and exciting possibilities!

The first and most obvious change you will see is that now, you can hover over Dungeon Portals to see a more exhaustive description of the Dungeon Mods it has. You can also see more things like the Difficulty rate of a particular dungeon and its Grade.

Once you are inside a Dungeon, you can quickly see the Dungeon Mods applied to it. Press the “Log”  key (default: K) and you will see a list.

Bosses and Minions

Dungeon Mods target either “bosses” or “minions”. But we know this is a broad categorization, so expect some flexibility for each specific case. 

Realm has a lot of variety and there are multiple “weird” cases: secret bosses, multiple bosses, minions that are really entities spawned from a boss, etc.

In all cases, Dungeon Mods targeting Bosses that give some kind of reward, like additional or extra loot, are applied to only “one” entity in the dungeon. 

However if the Dungeon Mod affects gameplay (for example the “Tough Boss I“ will make the boss have more Defense) it will also affect minibosses and anything we consider part of the fight itself, like soldiers that spawn directly from the boss, as they can’t really be considered “minions” in the sense of them being an integral part of the boss fight.

In case of multiple and secret bosses, the same philosophy is followed. Any gameplay-affecting Dungeon Mods are applied to all these entities, but only one of them can give you the reward/loot/XP benefits if there’s a Dungeon Mod with such an effect.

Each case is different and we will be reviewing the data and feedback as we adjust the feature in future releases.

Multiple-level floors

In general, and with some exceptions, if a dungeon has Dungeon Mods applied to it and it has multiple levels (for example you can descend to the Inner Sanctum through the Ice Cave), the inner levels will keep the same Dungeon Mods as the dungeon you come from. 


A new element linked to the Dungeon Mod system is the Grade of the dungeons. There are 5 Grades a Dungeon can be ranging from Grade D (the lowest) to Grade S (the highest). 

You can think of the Grade as how “intense” Dungeon Mods can be on a Dungeon. For example, a Grade D Dungeon will only have Dungeon Mods that are quite moderate (either for the good or for the bad). However, for a  Grade S dungeon, the most extreme Dungeon Mods can apply, but that also includes the most desirable rewards.

There is some variability, but there is a set maximum number of Dungeon Mods that each Grade can hold:

GradeMaximum number of Dungeon Mods
Grade D2 Dungeon Mods
Grade C3 Dungeon Mods
Grade B3 Dungeon Mods
Grade A3 Dungeon Mods
Grade S4 Dungeon Mods

Risk and Reward

Although luck is involved in the system, the Dungeon Mods tend to balance risk and reward. That means that if you get a very powerful “risk” (for example a Dungeon Mod that makes the enemies more resistant) the system will try to pair it with a similarly powerful “reward” (for example a Dungeon Mod that increases the loot you get from it!).

Bear in mind that by design this balance is not strict, which means that luck plays a factor. 

Sometimes dungeons will be slightly tweaked towards being more or less difficult, but the threshold is usually towards balance. The overall difficulty change (that will either make it easier or more difficult) is reflected in the total Difficulty score of the dungeon that you can see in the tooltip. 

Key Refinement

When it comes to Keys, things get interesting.

For starters, you can use your old, trusted keys as you have till now. They will just open the dungeon without Dungeon Mods. You can use them to play the Dungeon “as is”.

However, Keys can have Dungeon Mods now. The Key’s tooltip will show you any Dungeon Mods (and Grade) applied to it, if any. That means that you will know which Grade and Dungeon Mods the dungeon will have before opening it!

Notice also the little new addition at the bottom of the tooltip:

Use CTRL(CMD in Mac)+Click on the Key to open the Key Refinement Panel.

From this panel, you can see any Dungeon Mod the Key has (if any). The neat thing is that you can also manipulate the Key if you don’t like the Mods it has! This opens a whole new world of possibilities.


For one, you can Upgrade or Downgrade your Key to change it to a higher Grade. Bear in mind the upgrading operation has a Gold cost.

For example, let’s say you got a C-Grade Key for Fungal Cavern. It has some Dungeon Mods, but you want to step up the challenge for yourself and your guildmates. Of course, you want to also try and get better rewards from it! 

So you can try to Upgrade your key to the next Grade (Grade B). The current Dungeon Mods will be discarded and new ones (now within the power appropriate for Grade B) will replace them.

Beware that this operation will remove all the Dungeon Mods the Key has and replace them with new ones that will be “re-rolled” according to the new Grade the Key has! 

It’s not possible to selectively remove specific Dungeon Mods.

In case you are wondering, there’s no limit for a Dungeon to be upgraded (or downgraded), from D to S tier. So it’s perfectly possible to play a Grade-S Pirate Cave. Prepare for a whole new experience!


You can always do the opposite operation and “downgrade” a key to one Grade below. Same as with upgrading, it will remove all Dungeon Mods and reroll them in the Grade below. 

Downgrading is a free operation.


There’s also the possibility of just re-rolling them without changing the Grade. This operation, same as Upgrading, has a cost in Gold. 

Reset your key

If you want the “vanilla” experience, you always have the possibility of “resetting” your key and transform it into a normal key, for free.  

If a Key is reset to a normal key, all its Dungeon Mods will be removed and it will just open the normal version of the Dungeon.

Upgrade a non-modded key

The reverse operation is also possible: you can convert a normal Key into a modded Key through the Key Refinement panel. It will become a D Grade Key with random Mods, which of course you can also upgrade or reroll as you want. Bear in mind that converting a normal Key into a modded one also has a cost.

For the time being, you can meddle with Keys as you want, but in the future, we want to offer you unique possibilities thanks to our unique Key Refinement system.

Keys with unique playstyle combinations, twists on existing dungeons for solo PPE players, and all kinds of “challenge” Keys that we hope will be really fun and varied!

Overall, we hope you like this new system. As a new layer in the game systems, it brings exciting possibilities that we want to expand upon. We will also stay vigilant and see how it develops, gather data, and listen to your feedback.

This section contains a list of dungeons that can spawn in the realm (and a few relevant others, like some event-tied dungeons). You can see the probability of each dungeon spawning with a certain Grade, which will determine how good the “extra rewards” are (and also how riskier it gets for compensation). Remember a dungeon can also spawn without Dungeon Mods at all.

At present time; Oryx’s Castle, Wine Cellar, Oryx’s Sanctuary and Court of Oryx don’t naturally generate with Dungeon Modifiers. Certain other dungeons that you don’t see here have different particularities or don’t spawn with Dungeon Mods at all.

Dungeon Keys do not follow this system, as they can be upgraded or downgraded to any Grade you want, or be stripped of all mods if you desire so..

Dungeon Mods sorted by Grade

In order to better check which Dungeon Mods can appear in which Grades, here is a quick reference. The Dungeon Mods marked with ” 🟆 ” tend to appear with high probability, although only one of them can appear at once.

Additional Tables


Souvenir I and II increase the chance of an “iconic” piece of UT gear, usually typical or highly desired in that dungeon. The iconic piece is the same for both Souvenir I and Souvenir II.


Chef is a Dungeon Mod that can drop a food item depending on the dungeon.

Pet Collector

Pet Collector is a Dungeon Mod that can drop a pet egg, depending on the dungeon. It will never drop an egg with a rarity over Rare.

A note on multi-level dungeons: Some multi-level dungeons can have different associated items for Chef, Pet Collector and Souvenir Dungeon Mods. Some of them don’t even have a boss like Ice Cave (which boss is in the Inner Sanctum) but we have still defined data for them in case of events or future Dungeon Mods that make use of this feature.
