Calculations

Rate calculation

What's the difference between +50% and x50, or how to calculate the Premium bonus?

• Correct: Rate x1 + 50% bonus = х1,5
• Incorrect: Rate x1 multiply by 50 = х50

Total: bonus = х1,5

Group bonuses

The logic behind Premium Account operation in a group:

• EXP/SP — a personal bonus and does not depend on the PA of other characters in the party
• Spoil — only the spoiler's bonuses are used for calculation. The bonuses of all other characters do not affect the spoiler
• Drop — the final bonus depends on the amount of damage dealt to the monster by each character in the party

Damage calculation

Drop bonuses depend on the PA of each character that deals damage to the monster. The calculations use a percentage of the damage dealt to the monster's total HP.

Formula: (R * X1 * Y1) + (R * X2 * Y2) + (R * X3 * Y3) ... = Z

• Z = Total bonus in the party
• R = Base server rate, default = 1
• X = Percentage of damage dealt. 100% = 1 / 50% = 0.5 / 30% = 0.3
• Y = Character rate, including PA bonuses
• 1, 2, 3...9 = Party character number

Examples of calculations based on drop bonuses:

Example 1:

• Character 1 with PA dealt 50% damage to the monster
• Character 2 without PA dealt 50% damage to the monster
• Other characters did not deal damage to the monster
• Z = (1 * 0.5 * 1.5) + (1 * 0.5 * 1) + (1 * 0 * 1) = 0.75 + 0.5 + 0 = 1.25 = 125%

Example 2:

• Character 1 with PA dealt 90% damage to the monster
• Character 2 without PA dealt 10% damage to the monster
• The other characters dealt no damage to the monster
• Z = (1 * 0.9 * 1.5) + (1 * 0.1 * 1) + (1 * 0 * 1) = 1.35 + 0.1 + 0 = 1.45 = 145%

Example 3:

• Character 1 with PA dealt 30% damage to the monster
• Character 2 without PA dealt 70% damage to the monster
• The other characters dealt no damage to the monster
• Z = (1 * 0.3 * 1.5) + (1 * 0.7 * 1) + (1 * 0 * 1) = 0.45 + 0.7 + 0 = 1.15 = 115%
