The tables go by weapon type: bows, crossbows and daggers are Knight Online's rogue weapon types. BianKO's exchange page gives the type (it lists Iron Crossbow as a Bow and Cleaver as a Dagger); for items not on that page, the word in the name decides (Horn Crossbow, Assassin Dagger).

Mobs under level 50 drop starter weapons at high plus: Bow (+2 to +8), Short Bow (+5/+6/+7) and Dagger (+4). Kukry, Wrist Cutter, Knife and Stiletto have no type on the site, so they're left out of the table.

+3, +4 and +5 bows and daggers: exchange boxes

From mobs, Shard and Iron Bow stop at +1; the +3, +4 and +5 versions are in exchange boxes. Outside Abyss Gem the percentages don't add up to 100%, so read them as relative odds.

Item rental and converters

Item rental went live with the April 28, 2025 patch: buy a Stone of Rogue from Sundires, put it in Shozin and you get +7 armor, a +7 weapon and +0 accessories. The patch note doesn't say which weapon.

The Power Up Store sells the Arrow of ‹selfname› Converter and Dagger of ‹selfname› Converter for 1,499 KC, and Random Item Exchange Gem lists Dagger of ‹selfname›(+1) at 0.295% and Arrow of ‹selfname›(+1) at 0.246%. The site doesn't explain what the converter does.

FAQ

What is the bow and dagger drop rate on BianKO?
The site doesn't list it. Mob pages only show the item list, with no rates.
Where does Chitin Bow drop?
On the mob pages, only in the main drop of the Lesath records. Black Treasure Chest also lists it at 1.19%, but no mob page shows that chest as a drop.
Is Mirage(+5) a rogue weapon?
No. BianKO's exchange page lists Mirage as a Two-handed Sword. The rogue version is Mirage Dagger(+5), at 0.653% in Random Item Exchange Gem.
Can a +5 Shard drop from mobs?
Mob pages top out at Shard +1, with Hepas Exceptional Shard at +7. Shard(+5) is in Random Item Exchange Gem, the Platinum Exchange Box and four Dark Fragments.
