Hourly BUS income is based on the 2,200,000 coin BUS price in our data. If your server's price differs, change it in the Farm Calculator.

Don't pick a slot on the BUS rate alone

BUS is a small part of the income in every slot. Paramun gives 1.2 BUS per hour, which is 2,640,000 coins. But the same slot's total gross income is 25,890,000 coins per hour. So BUS is only 10% of Paramun's income.

The place where BUS has the highest share is CZ - Apostle of Cold: 20% of the hourly gross comes from BUS. That's not an advantage, it's a warning. In that slot, in the hours where no BUS drops, you're left with less.

In short, treat BUS as a bonus. Pick the slot by the sum of fixed coins, junk income and the other drops.

How much of the total income is BUS

CZ - Apostle of Cold 8,792,500 1,760,000 20%
Eslant - Apostle of Cold 11,475,000 1,870,000 16%
Lufer - Grell 3,700,000 550,000 15%
Eslant - Paramun 25,890,000 2,640,000 10%
Eslant - Raven Harpy 14,020,000 1,320,000 9%
CZ - Balrog 11,790,000 660,000 6%
CZ - Evil Wizard 14,250,000 770,000 5%
Eslant - Giant Golem 19,350,000 880,000 5%
Eslant - Dark Knight 20,135,000 660,000 3%

Gross = fixed monster coins + junk/NPC income + hourly value of all drops. Before expenses.

BUS by zone

  • Eslant: BUS in all 13 of 13 slots. The widest zone for hunting BUS.
  • Lufer: BUS in 12 of 13 slots but the rates are very low. Highest is Grell at 0.25, lowest is Hornet at 0.02.
  • CZ (Ronark Land): BUS in 8 of 10 slots. Apostle of Cold leads with 0.8.
  • Delos: BUS in only 2 of 7 slots. Hobgoblin 0.12 and Burning Skeleton / Phantom 0.08.

Why BUS is in such demand

BUS is the main material for upgrading items at the Magic Anvil. By our anvil data the BUS rates are: +4 to +5 75%, +5 to +6 55%, +6 to +7 30%, +7 to +8 10%, +8 to +9 1%. There is no +9 to +10 with BUS, the rate is zero.

Those rates explain the BUS demand. Someone going for +8 burns 10 BUS on average. Someone going for +9 burns 100 on average. Add a Trina's Piece and +7 to +8 goes to 30%, +8 to +9 to 2%. Trina cuts the BUS need to a third, but Trina has its own cost.

Blessed Upgrade Scroll also appears in the Narki pools. It's on the list in all three of the Middle Class, High & Rebirth and Unique categories.

If your character is 8 or more levels above the monster, the monster gives you no boxes or coins. A level 78 character can't get BUS from level 70 Apostle of Cold.

Before you go BUS farming

  • Check the level gap first. If you're 8 levels above the monster, that slot gives you no boxes at all, whatever the rate.
  • Compare the slot's total gross income, not the hourly BUS count. The slot with the highest BUS share is usually not the one that earns most.
  • In slots where pot cost is Very High, BUS income may not cover the cost. Our default cost is 2,971,667 coins per hour.
  • Enter your own server's BUS sale price in the Farm Calculator. The 2,200,000 in our data is only an example price.
  • Rare drops mislead over short runs. In a slot with a 0.08 rate it's normal to see no BUS in an hour, don't panic.
