Enter
In the lobby, use the AFK NPC identified as Luc, described as a shinigami-like figure, or the AFK menu prompt. Entry is free. The client tracks time. Collect by opening the AFK screen again or by leaving for the normal lobby. Read the timers on your own screen; they were adjusted during early access.
What the launch tests recorded
| Result | Reported rate or rule |
|---|---|
| Luc, also spelled Luke | about 0.55% |
| Gems | 5% for about 10 gems |
| Gold or Yen wording | 40% for about 100 |
| Food | periodic, no percent published |
| Trait rerolls | periodic, no percent published |
| Yamcha | 4-hour early-access milestone |
| Early-access entry | 9-hour pre-launch milestone |
The 4-hour and 9-hour rows are early-access milestones. A 399 Robux instant early-access bypass was also mentioned for that period. Do not buy anything on the assumption those milestones still exist after the release title went live. The Luc, gem, and gold cycles are the part to check on the current panel.
Luc is a Secret support and a reason to AFK if banner luck missed Broly and Gojo. The chamber does not drop the finger item used to evolve Sukuna.
When to sit in it
Use it overnight, or after your Story loop fails and the daily challenge is done. If Namek Act 3 Nightmare still clears in about half a minute, that active loop produces more gems than a 5% chance at 10 gems. Keep a free inventory slot. The base cap is 50 units, and a full box can waste a character drop.
The Luc calculator on the tools page treats each reward cycle as one attempt. It does not know how many minutes a cycle is.
