Model & Data

Estimated probabilities for direct damage. A seeded Monte Carlo simulation estimates casts to kill. Typical, reliable and near-certain results use 50%, 95% and 99% cumulative probabilities. We use 2,500–100,000 trials and up to 2,000 casts. A 100% sample result is not a guarantee.

Mechanics and assumptions

Physical damage uses independent uniform stat and 80–100 base rolls. Swing/stab probabilities are 60%/40%. Dagger attacks use stab, and Lucky Seven uses a 3.0 weapon multiplier.
Magic damage is sampled uniformly between the minimum and maximum determined by skill mastery.
Misses and critical hits are independent per hit. Animation and Spear Mastery defense-ignore rolls are shared within a cast. Client random-number correlations have not been verified.
Apply defense, element, level penalty, critical damage and Iron Arrow attenuation, then floor each hit and cap at 99,999. Elemental immunity causes zero damage.
Final Attack is modeled as the selected direct attack using the appropriate class and weapon table. No random extra attack is added to other skills.
Monsters start at full HP without healing. Attack speed, MP depletion, buff expiration and attacks by other players are excluded.

Excluded damage

Poison, burn and axe bleed damage over time are excluded. Results may differ when these effects are counted. Heal against undead is not supported because its separate formula is unverified; Cleric supports Magic Claw and Holy Arrow. Third and fourth job skills are outside this launch-client dataset.
