Every mob page on BianKO's site has two lists, basic drops and group drops, with no rates and no map. The exchange page shows box contents with rates, but outside Abyss Gem the percentages don't add up to 100%, so treat them as relative odds.

Yellow Sand, Pidama and KING Worm were added as special bosses in the April 25, 2025 patch, which also gave Isiloon and Felankor +1 accessory drops. There's no mob called "KING Worm" in the database; Worm (700) may be that boss, but the site never links the two.
FAQ
Where can I see drop rates on BianKO?
Not on the mob pages. The launch post lists an in-game drop search that shows rates, but its detailed forum thread wasn't archived.
Which map is each mob on?
Detail pages don't show a zone; only the mob search results have a zone column. The Garden, Bowl and Ronark Land pairings come from the patch notes.
Are the exchange percentages real odds?
Only Abyss Gem adds up (99.5%). In the other boxes the totals are tiny, so use the numbers to compare items against each other.
What's the fastest way to get Trina?
Buy a Trinas Piece in the store for 60 AB. The only mob source is Atross, and its rate isn't listed.
