Rejoining

When you leave the server, the game deletes a chunk of your XP and hands you back permanent Rejoin Multiplier for it. The multiplier never resets on its own.

How much you lose

Loss percentage is set by your tier, and it is deliberately brutal at the top:

Tier range	XP lost
Below 19 (under Divine)	1 %
19 to 26	10 %
27 to 36	30 %
37 and above (Unlimited+)	70 %

That percentage is then reduced by your gamepasses, and a flat loss barrier is subtracted from what remains:

lost    = TotalXP x percent x lossMulti
lossMulti = 1 - 0.2 (LossPrevention) - 0.1 (Crown)
barrier = 10 000 + 100 x RejoinMultiplier
        + 100 000  (LossPrevention)
        +  50 000  (Crown)
final   = max(TotalXP / 1000, lost - barrier)

The floor is TotalXP / 1000 — you always lose something, no matter how big your barrier is.

What you get back

The lost XP is converted with GetMultiGain:

multiplier gained = PowerMulti(tier of the lost XP)^2 x GlobalRejoinBoost

GlobalRejoinBoost is a server-wide value that Hyper Star SacrificeBoost events raise by 1.1x for an hour, so rejoining during one is worth measurably more.

On top of that, 15 % of the multiplier gain plus 1 000 drops as orbs at your last position — unless you died, or you were standing inside the spawn area when you left.

Caution

Dying before you leave, or leaving from spawn, throws away the orb drop. Walk out onto the map first if you want to catch it on the way back in.

The rejoin chain

Each leave increments RejoinChainCount, worth +5 % idle XP each, capped at 4x. The chain timer gains 60 seconds per join and caps at 600 seconds. When the timer expires the count resets to zero.

Short, repeated sessions beat one long session. This is the intended rhythm of the game.

Auto-rejoin

Auto-rejoin is unlocked either by Roblox Premium or by reaching HighestTier >= 13 (Mythical). It runs the loop for you.

Reading the numbers

• Under Tier 19 you lose 1 %, and the barrier often eats most of that. Climb.
• From Tier 37 up, a leave costs 70 % of everything. That is the point where you plan the leave rather than just doing it.
• Loss is calculated before the barrier, so at low multipliers the barrier can absorb almost the entire loss.
