April 28 patch note "Starting level fixed at 83" April 28, 2025

Two numbers are certain: levels stop at 83 and rebirths at 6. The requirements (EXP, items or coins), what each rebirth gives in stats or points, and which NPC handles it aren't explained anywhere on the site. The launch post's rebirth line pointed to a forum thread, and that thread is gone with the forum.

Since April 28, 2025 new characters start at 83, so there's nothing left to level. The patch note doesn't say what rebirth count a fresh level 83 character has either.

What is the [REB +4] Random Quest Box

The only item with the rebirth tag in its name sits inside the Black Treasure Chest: [REB +4] Random Quest Box, type "Quest", shown at 0.16%. The site doesn't list what's inside or whether the "+4" means rebirth 4.

The Black Treasure Chest holds 46 items; the top one is the Blue Chitin Shell Armor Exchange Voucher (13.333%). Its rates add up to 78.7%, not 100%, so read them as relative odds. No mob page lists the chest as a drop.

The only mob with rebirth in its name is Death Rebirth (9691): level 90, 54,370 HP, Blessed Upgrade Scroll as its basic drop. Its page doesn't tie it to the rebirth system.

Where your power comes from at level 83

With rebirth details missing, these are the ways to scale a level 83 character that the site lists with actual numbers:

Accessories use their own Trina: the Accessory Trinas Piece is 100 AB in the store and lifts +0→+1 to 82.5% and the next two steps to 75%. Beyond the launch week and the reset fee, the site doesn't list a point cost per perk.

FAQ

What's the max rebirth on BianKO?
6. The launch post writes it as "REB 6 Son", meaning 6 is the last one.
Which NPC does rebirth on BianKO?
The site doesn't say. That was in the forum thread on the rebirth system, and no copy of it survived.
Does rebirth give stat or skill points?
BianKO's site has no per-rebirth bonus list. So there's no number to quote here.
How do I get the [REB +4] Random Quest Box?
By opening Black Treasure Chests, where the site shows it at 0.16%. Where the chest itself comes from isn't listed.
