EXP Calculator

How many mobs and hours to the target level and reverse? Pick your level and the mob you kill. See how much premium and scrolls cut the time.

Character
Reverse fields open only with level 83 selected.
Remaining EXP = the level's total bar EXP × remaining percent ÷ 100.
Kills and party
Picking one fills EXP per mob and hourly pace together.
The mob's base EXP. Party factor and bonuses apply on top.
Mob EXP isn't divided by headcount; it's multiplied by the factor in brackets.
EXP bonuses

Enter the percentages written on your package and scroll. The tool adds them all into one multiplier.

EXP Premium: +120%.
EXP Flash: +50% to +80% depending on premium type.
Event, server bonus etc.

How does the math work?

The tool first adds up the bar EXP of every step in between. It subtracts the part matching your current percent. What's left is your total EXP needed. EXP per mob = base EXP × party factor × bonus multiplier (rounded down). Total EXP divided by that and rounded up gives the mob count. Mob count divided by hourly pace gives the time.

Every value in the table is the EXP needed to go from that step to the next. After 60 the bar grows seriously at every level. You'll see it clearly in the list below.

At level 83 100% you reverse for 10,000 NP and 1 GB. Every reverse asks 10% more EXP than the one before (the 83/0 bar is 8,705,986,960). The tool computes this compounding up to 83/15.

Tips
  • In Eslant, Paramun and Brahman are in the safe zone, good for steady farming.
  • In CZ, Titan and Dark Stone give the highest base EXP but need a solid party.
  • Don't guess the pace, count it: kill for 10 minutes and multiply the mob count by 6.
  • See the mob guide for mob locations and levels.
  • Before buying EXP premium, look at the payback calculator.

The base EXP and hourly pace on the mob buttons come from current USKO slot data: Paramun 60,000 (8 a minute), Brahman 45,000 (10), Titan 110,000 (4), Boro 85,000 (5), Dark Stone 140,000 (3), Booro 95,000 (4.5), Falcon 75,000 (5). If your server differs, change the field by hand: kill one mob, see how much your EXP percent rises. Mob EXP ≈ your level's total bar EXP × percent gain ÷ 100.

Mob EXP isn't split evenly by headcount. Each person's share has a factor: solo 100%, 2 players 60%, 3 players 46%, 4 players 40%, 5 players 36%, 6 players 33%, 7 players 31%, 8 players 30%. So in an 8-player party everyone gets 30% of the mob — in total the mob gives 2.4× EXP. A big party lowers the per-person share but kills mobs much faster, so hourly gain goes up.

At level 83 100% you reverse for 10,000 NP and 1 GB. The 83/0 bar is 8,705,986,960 EXP. Every new reverse level asks exactly 10% more than the previous: 9,576,585,656 for 83/1, 10,534,244,221 for 83/2 and so on. The tool computes this up to 83/15.

Added: 120% premium + 50% flash = 2.70 multiplier. EXP per mob = base EXP × party factor × multiplier, rounded down. If your server has an extra multiplier, add it in the "Other (%)" field.

Private servers can use their own table. If you're on one, switch to "Total EXP by hand" mode and enter your remaining EXP directly.
