Group loot — the standard option included in the service. Loot is rolled under the in-game system, so the exact number of items you receive can’t be guaranteed, especially in a single-boss run.
After purchase, we confirm details in chat or by email and schedule the run time.
Self-play: you get an in-game invite and summon at the agreed time.
Piloted / Remote Control: we guide you through the setup after checkout.
Important: hit the boss at least once to be eligible for loot.
If needed, you can stay alive and follow basic instructions, or die after the pull — follow the raid lead’s call.
No — it’s a final boss only run, so you don’t need a full Voidspire clear.
