Priest Cracker, Priest Bone crasher, Priest Impact, Priest Hacker and Priest Spike Club say they're priest weapons in the name. The rest of the table goes by weapon type: maces and two-handed maces (impacts) are Knight Online's priest weapon types, and BianKO's exchange page gives the type (Impact is a Mace, Iron Impact a Two-handed Mace).

Plain Cracker, without Priest in the name, shows up in 146 mob records (Centaur Sniper, Ranger and Archer included), but the site gives no type for it. Large Breaker, Large Hacker, Maul and hammers like Lycaon hammer are in the same spot, so they're not in the table. Below level 50, Mace (+7) drops as a starter weapon.

+3, +4 and +5 priest weapons: exchange boxes

From mobs, Priest Impact and Impact stop at +1; the +3, +4 and +5 versions and Hell Breaker come from exchange boxes. Outside Abyss Gem the percentages don't add up to 100%, so read them as relative odds.

Item rental and +8 upgrades

Item rental went live with the April 28, 2025 patch: buy a Stone of Priest 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.

FAQ

What is the priest weapon drop rate on BianKO?
The site doesn't list it. Mob pages only give the item list, with no percentages.
Are Priest Impact and Impact the same item?
No, the site lists them as two separate items. Impact has the Mace type; Priest Impact has an empty type field, but the name marks it as a priest weapon.
Where does Hell Breaker come from?
It's not on any mob page. The highest listed rate is in Black Treasure Chest (2.381%), and it's also in Random Item Exchange Gem, the Ornament box and Dark Fragment of Lust.
Can a +5 Priest Impact drop from mobs?
Mob pages only have Priest Impact at +1. The +5 is in Random Item Exchange Gem, the Ornament box and the Pride, Gluttony, Envy and Greed Dark Fragments.
