Witcher Monster Slayer Calculator — Damage & Rounds to Kill

Formula

How this is calculated

The Witcher: Monster Slayer (2021, AR mobile game) does not publish its exact internal damage formulas, so this calculator uses the standard RPG damage model consistent with community gameplay observations. Each sword strike has a base damage equal to your Attack Power stat. When a critical hit occurs — happening with probability equal to your Critical Hit Chance — the strike is multiplied by the Critical Hit Multiplier (e.g. 200 % means double damage). Over many swings, the statistical average per hit is: Attack × [1 + critChance × (critMulti − 1)], where critMulti is expressed as a plain multiplier (2.0 for 200 %).

Signs provide additional area-effect or damage-over-time damage each round. The approximation used here is that a sign contributes roughly half its Sign Power stat as direct damage per combat round — this is an estimate, as the actual value depends on the sign type (Igni deals more direct damage than Quen or Axii). Combining the sword average with the sign contribution gives the expected damage per round. Dividing the monster's HP by this figure and rounding up gives the expected number of rounds to defeat it.

Actual combat in the game is affected by timed QTE events, debuffs, monster resistances, oils, potions, and other bonuses not captured here. Use these numbers as a planning estimate rather than a precise prediction.
