Drug Price Calculation

The General Formular

$$P_{total}=N\times I_{Inflation}\times (M_{ItemPrice}+\sum _{i=1}^n[(a+b\times e^{L_i}+\frac{t_i}{20}\cdot c)\cdot f_i])$$

After inserting the general values it may look like this (retrieved on November 26, 2025):

$$P_{total}=N\times I_{Inflation}\times (M_{ItemPrice}+\sum _{i=1}^n[(500+10e^{L_i}+\frac{t_i}{20}\cdot 1)\cdot f_i])$$

• $N$ = Number of items
• $I_{Inflation}$ = The Inflation Factor (Stays at 1.0 for now)
• $M_{ItemPrice}$ = Item Price in the Shop
• $n$ = Number of effects
• $L_i$ = Level of effect i (converted from NBT byte)
• $t_i$ = Duration of effect i in ticks
• $f_i$ = Effect multiplier (2.0 for good effects, 1.0 for others)

General Values

• a = EFFECT_BASE_PRICE
• b = AMPLIFIER_MULTIPLIER
• c = DURATION_MULTIPLIER
