2026 summer test

Dear Tibians,

beyond the final steps of Make Believe, a radiant entity awaits those who dare to face it: Phosphorus.

In this thread, you can give your feedback on this boss encounter. If you have feedback about the quest, other bosses or the UI of the new difficulty system, please share it in the corresponding threads.

Phosphorus is a Nemesis Boss and can be challenged every 68 hours. As the final opponent of this quest, Phosphorus is meant to be the most demanding encounter of this summer update 2026. This fight uses the new difficulty scaling and will require teams to coordinate efficiently, master the encounter's mechanics and make full use of the strengths of different vocations.

For this boss fight, we are especially interested in your feedback regarding the following topics:

• What was, in your opinion, your vocation's primary role in this fight?
  
• Were all of the mechanics clear to you, or did you have trouble understanding any of them?
  
• What difficulty did you choose?
  
• If you chose a difficulty with additional mechanics, how did these mechanics change your approach to this boss fight?

It also helps us if you let us know when (e.g. before or after a specific change) and how you tested something so that we know which version you are referring to.

Please keep in mind that you can use the voodoo doll to reset the cooldowns of the new bosses.

Hello valiant boss slayers of Tibia,

We hope you are enjoying the new boss fights from the Make Believe quest. Based on our data and your feedback, we have decided to implement the following changes to make these encounters more challenging:

Phosphorus

• We have significantly increased the damage output of both forms of Phosphorus. Also, the final form can no longer be challenged and will change targets more frequently.
  
  
• We have increased the healing and damage output of moonsilver sentinels to make attacking them a higher priority.
  
  
• Moonsilver storms can now inflict rooting.
  
  
• We have also significantly increased the damage caused by draining rifts, as well as the environmental death and holy effects in the final boss room.
  

We are excited for you to try out these changes and tell us what you think.

Kind regards and happy boss slaying,
Ilyndor

Dear Tibians,

Before the weekend starts, we have prepared some changes to the Make Believe boss fights to make them more challenging. These changes should go live with this afternoon's patch.

Phosphorus

Stage 1

• Increased the damage output and self-healing of Phosphorus.
  

Stage 2

• Increased the damage output of the empowered versions of Mimar Haffar and Maior Domus.
  
• Reduced the sensitivities of the empowered version of Maior Domus and increased his healing output.
  
• The empowered version of Maior Domus can no longer be challenged. We want to make it more difficult to keep the two bosses separated from each other.
  

Stage 3

• Increased the damage output and self-healing of Phosphorus.
  
• Reduced the sensitivities of Phosphorus.
  
• Phosphorus can now increase his own speed and inflict fear.
  
• The curse now happens more frequently and deals increased damage.
  
• Disruptive energy now deals increased damage.
  
• Phosphorus will now be aided by moonsilver augurs.
  

Please try out these changes once they go live and let us know what you think.

Have a nice weekend,
Ilyndor

Dear Tibians,

We have fixed a bug that caused players to continue receiving damage after leaving the boss room if Phosphorus' curse was still active.

Best regards,
Ilyndor

Hello Tibians,

With this afternoon's patch, we have increased the damage output of the rivals during the first stage of this boss fight.

Just here to report a bug, it seems like Mimar Haffar fails to teleport into the walkable area on the 2nd phase after Maior Domus dies if there's a player standing on the bottom right tile of the square in the middle

Thank you for the report, this has now been fixed.

That also made me wonder if you can simply kill Mimar Haffar from afar while ignoring Maior Domus and proceeding with the fight or if there's a check for whether both bosses are slain.

That is indeed possible.

Best regards,
Ilyndor and Jasuin

Hello Tibians,

We have decided to significantly increase the experience gained from the Phosphorus boss fight from 2,500,000 to 16,000,000 to be more in line with the bosses from Rotten Blood.

In addition, we have fixed a bug that caused the curse in the final stage to always target the same player instead of selecting a random one.

Please note that these changes won't be included in this morning's patch.

Best regards and happy testing,

Ilyndor

Dear Tibians,

As the test server is coming to an end, we would like to take a moment to thank you again for your continued feedback over the last two weeks.

Your reports and suggestions, combined with our data, helped us fine-tune the Phosphorus encounter and identify several areas where we wanted to improve the pacing and overall challenge of the fight.

Please note that on the live servers, the additional mechanics will start to trigger at difficulty levels 10 and 25 instead of 10 and 15.

We will also make the following changes:

Stage 1

• Rivals will now respawn more quickly after the previous rival has been defeated.
  
• Significantly increased the damage output of the rivals, especially against players who do not face their designated rival.
  

These changes are intended to make the first stage less time-consuming while also making it more challenging.

Stage 2

• The empowered version of Maior Domus will now retarget more frequently.
  
• Significantly reduced the respawn time of moonsilver sentinels to keep the pressure on players throughout this stage.
  

Stage 3

• Reduced the duration of the fear effect to 3 seconds to make it more manageable alongside the additional mechanics in the room.
  
• Moonsilver augurs will now retarget more frequently.
  
• Reduced the respawn time of moonsilver augurs.
  

We are also looking into a bug where Phosphorus' curse is not renewed if the affected player dies while still inside the boss room. In addition, we will investigate ways to make the cleansing field more visible.

We hope you will enjoy facing Phosphorus on the live servers. Once the content goes live, please continue to share your feedback and let us know what you think.

Take care, and as always, happy boss slaying,

Ilyndor and Jasuin
