A free web-based tool designed for Ragnarok X: Next Generation players to calculate base multipliers and optimize stat distribution for maximum DPS output.
Why was this created?
The community spreadsheet was solid for quick checks, but only covered 3 stats. I added the remaining in-game stats for more accurate calculations that better match actual damage output
What are the features?
Base Multiplier Calculator
Multi-Target
Specific MVP/Mini
Average boss level per size
Stat Optimization Engine with randomized recommendations based on your stats
Equipment Set Bonuses including Vesper, Blue, and White sets
Flash Simulation for Spear of Eternity and Reaper Scythe
Progressive Web App with exclusive features when added to your home screen:

How to Use
Dropdowns
Select your Attack Type, Weapon, and Weapon Attribute.
For MVP/MINI:
Choosing a specific MVP/Mini will automatically sync and lock its size, race, and attribute.
(For example: Phreeoni = Large / Brute / Neutral. These fields stay locked, you just need to fill in the numbers.)
If you only have a Race enchant (or only Attribute), set the other field to 0.
Example: Brute 0 / Neutral 20
Example: Brute 30 / Neutral 0
Choosing Average Lv. lets you manually set or skip the target race/attribute.
If you don't have race and/or attribute enchants, just go with Average Lv. Boss and skip those fields.
Equipment
Select equipment set you're using (Vesper / Blue / White).
Stat Inputs
Enter your stats exactly as they appear in-game.
Extra: Final DMG Bonus %
F. P/M DMG BONUS
Check detailed stats for Final Damage Stack / Final Damage Bonus. Make sure no buffs are active. If you don't see it, just set it to 0.
Only numbers, don't type "%".
Decimals are fine. (Example: 888.88)
Calculate
Once everything's filled in, hit Calculate.
Results
You'll see the base multiplier and a breakdown of your stats.
Simulate Flash
Spear of Eternity and Reaper Scythe.
Each has 10s duration / 20s cooldown with +84% or +28% bonus. This tool normalizes them to 42 and 14 for 100% uptime in flash bonus contribution. But it still uses the original values for calculations.
Swap Target
Lets you switch bosses without starting over.
If the new boss has different size/race/element, the inputs unlock and you'll need to re-enter your stats.
If it's the same type, the calculation updates instantly.
