In Path of Exile 2, endgame content is built around challenging pinnacle bosses that reward skilled players with powerful loot. One such boss is Kulemak, a dangerous Abyss-themed encounter that cannot be accessed through normal mapping alone. Unlike standard bosses that spawn naturally in maps, Kulemak requires a special key item known as Kulemak's Invitation.

If you want to challenge Kulemak without draining your resources by purchasing an invitation outright, there are specific methods you can follow to obtain one yourself. Below is a complete breakdown of where to farm Kulemak's Invitation, how to increase your chances, and how to use it once you finally get your hands on it.
What Is Kulemak's Invitation
Kulemak's Invitation is a special endgame item that grants access to the Black Cathedral, where the Kulemak encounter takes place. Without this invitation, the fight is completely inaccessible, regardless of your build strength or progression.
While some players prefer to buy the invitation directly to save time, others choose to farm it themselves to avoid spending currency and to make the most of their Atlas setup.
Where to Farm Kulemak's Invitation
The primary way to obtain Kulemak's Invitation through gameplay is by defeating specific Abyssal bosses. These bosses are Tasgul and Vandroth, both of which can be found in special endgame areas known as the Lightless Void and the Dark Domain.
These two Abyssal bosses are unique because they will always drop a Kulemak's Invitation when defeated. The challenge is not the drop rate, but actually finding the areas where these bosses spawn.
Finding the Lightless Void and Dark Domain
To encounter Tasgul or Vandroth, you must first locate an Abyssal Depths map. Once inside Abyssal Depths, there is a chance for an entrance to either the Lightless Void or the Dark Domain to appear. However, these areas will only start spawning once your character has reached level 79 or higher, making this content firmly endgame-focused.
To improve your odds of finding Abyss encounters, you should use an Abyss Precursor Tablet before opening your maps. These tablets significantly increase the chance of Abyss mechanics appearing, which in turn raises your likelihood of finding Abyssal Depths.
Additionally, investing into Abyss-related nodes on your Atlas passive tree can make a major difference. Proper Atlas setup not only improves spawn frequency but also makes farming invitations more consistent over time.
Defeating the Abyssal Bosses
Once you locate either the Lightless Void or the Dark Domain, prepare for a challenging fight. Tasgul and Vandroth are powerful Abyssal bosses with dangerous mechanics, especially if your build lacks survivability or sustained damage.
After defeating the boss inside one of these areas, Kulemak's Invitation will drop guaranteed. At that point, you can either use it yourself or sell it on the market for POE 2 Currency, depending on your goals.
