About the The Witcher: Monster Slayer Calculator
This tool estimates how a weapon-and-monster matchup plays out using the same damage-mitigation and damage-per-second (DPS) math that underlies combat in monster-hunting and action-RPG games, including the AR mobile title The Witcher: Monster Slayer. Enter your weapon's base damage, your attack speed, your critical-hit chance and multiplier, and the target monster's armor and health, and the calculator returns effective damage per hit, DPS, time-to-kill, and the number of hits required.
The formulas
Four values are computed directly from your inputs:
- Average crit factor = 1 + (crit chance ÷ 100) × (crit multiplier − 1). This spreads the extra critical damage evenly across every hit rather than simulating individual random rolls.
- Effective damage per hit = base weapon damage × average crit factor × (1 − monster armor ÷ 100). Armor is applied as a flat percentage reduction, the standard convention in action-RPG combat systems.
- DPS (damage per second) = effective damage per hit × attack speed (hits per second).
- Time to kill = monster health ÷ DPS. Hits needed = monster health ÷ effective damage per hit, rounded up to a whole hit.
How to get the best results
- Use your weapon's actual tooltip damage and your measured or listed attack speed, not rounded guesses — small errors compound through the multiplication.
- If a monster has different armor values per body part or phase, run the calculation once per phase and compare.
- Treat the crit factor as an average over many hits; any single hit is either a normal hit or a critical hit, not something in between.
Practical context
This is a general combat-math model, not a lookup of any specific game's hidden internal values — exact numbers vary by title, patch, and build. Use it to compare two loadouts against the same monster, or to see how much a crit-chance or armor-penetration upgrade actually changes your time-to-kill, rather than as an exact in-game prediction.
