How hit chance is computed, why skill accuracy bonuses are a percentage of your hit rate rather than flat HIT, and how much DEX you need to stop missing.
Your chance to land a hit is:
hit chance % = 80 + your HIT − the target's FLEE
capped at 100% and floored at 5% — you can always miss a little, and you can always connect a little. Your HIT is your base level plus your DEX, plus any flat +HIT on gear. A monster's FLEE is its level plus its AGI.
Several skills grant "accuracy", and it is a different thing from +HIT. Accuracy is a percentage of your hit rate, applied after the subtraction above. The Payon Stories wiki puts it plainly: if you would hit a monster 67% of the time, Bash Lv10's +50% accuracy takes you to 100%, not to 117 HIT.
| Source | Accuracy |
|---|---|
| Bash | +5% per level |
| Magnum Break | +10% per level |
| Pierce | +5% per level |
| Holy Cross | +2% per rank |
| Shield Chain | +20% |
| Sonic Blow (with Sonic Acceleration) | +50% |
| Weaponry Research | +2% per level (all attacks) |
Multiple sources add together into a single multiplier rather than compounding, so Weaponry Research 10 and Holy Cross 10 give ×1.40, not ×1.44.
Abysmal Knights are level 79 with 68 AGI, so 147 FLEE. At base level 99 your HIT is 99 + DEX. To never miss:
| Attack | DEX needed |
|---|---|
| Auto-attack | 68 |
| Holy Cross Lv1 (+2%) | 67 |
| Holy Cross Lv5 (+10%) | 59 |
| Holy Cross Lv10 (+20%) | 52 |
That is 16 stat points of DEX bought purely by the skill's rank — which is why the accuracy line on a skill is worth reading before you plan your stats. The calculator's Hit breakpoints panel does this for your actual build and target.
At base level 99 you need 52 total DEX when attacking with Holy Cross Lv10, or 68 DEX on a plain auto-attack. Abysmal Knights have 147 flee, and Holy Cross Lv10 adds 20% to your hit rate on top of your HIT.
No. HIT is subtracted against the monster's flee to give a hit rate; accuracy multiplies that hit rate afterwards. A skill with +50% accuracy turns a 60% hit chance into 90%, whereas +50 HIT would raise the hit chance by 50 percentage points before the cap.
Against most monsters yes, but perfect dodge is separate. A monster with high LUK can still dodge normal attacks outright, though that lucky dodge does not apply to skills.
The calculator prints every step of this with your stats, gear and target, so you can check the numbers rather than take them on trust.
