Hit Chance

There are some vague or non-exact figures and information on this page. Some spading is required.

[ Return to Game Mechanics ] The first, most important, step towards rifling through the pockets of a corpse is creating a corpse with pockets to be rifled. To achieve this lofty goal, one must first hit one's opponent. For regular, weapon-based combat, your chances to hit a given foe are determined by comparing your Attack to your opponent's Defense; the difference determines your chances to hit.
Your Attack is the buffed stat with which you are attacking: Muscle for melee weapons or mysticality weapons, and Moxie for ranged weapons. If you don't have a weapon equipped, then Muscle is used to determine your attack.
Your Defense is equal to your Moxie. Monsters skip all of the Muscle/Moxie nonsense and have straight Attack and Defense stats.
Hit Chance Formula
The exact hit rate mechanic is not linear, but this is a useful approximation suitable for almost all gameplay purposes:
Hit % = 6 + Attack - Defense × (100 - Fumble%) 11
For example: your Seal Clubber has 153 Muscle, lacks Eye of the Stoat, and is fighting something with 150 Defense.
Hit % = 6 + 153 - 150 × (100 - 4.545) = 78.1% 11
In other words: of the times you do not fumble, when your Attack equals your target's Defense there is a slightly better than 1/2, or 54.5%, chance to hit. For every additional point of Attack you have, add 1/11, or 9.1%, to your non-fumble chances to hit. For every additional point of Defense your target has, subtract 1/11, or 9.1%, from your non-fumble chances to hit. Below -6 Attack (relative to monster defense) you will always miss; above +5 Attack (relative to monster defense) you will always hit. At exactly -6 and +5 there is a zero chance of missing/hitting.
Some fraction of all attack attempts will be critical hits, and the rest of the hits will be normal. Given a fumble rate of fumbrate and a critical rate of critrate, the final outcomes are:
| baserate | = | ((6+attack-defense)/11), minimum 0 maximum 1 |
| fumble chance | = | fumbrate |
| normal hit | = | (1-fumbrate)*(baserate-critrate) |
| critical hit | = | (baserate) or (critrate), whichever is lesser |
| miss | = | (1-fumbrate)*(1-baserate) |
Regular Attacks Can't Miss
Certain pieces of equipment and effects grant the ability to never miss with regular attacks, although you can still fumble. These are:
- Equipment
- Effects
Notes
- When dealing with stats over 200 you start needing progressivly more attack over the monsters defense in order to always hit.
- Information about Monster Hit Chance can be found at Monsters.
History
- Before NS13, Mysticality was an attack stat if you were wielding a staff and had either Spirit of Rigatoni or a special sauce glove equipped. However, the introduction of mysticality weapons made this ability irrelevant, and they now allow the ability to wield chefstaves.
- Critical hits became automatic hits on March 27, 2008.
- The hit rate mechanics were quietly changed at some point after that, probably when monster criticals/fumbles were introduced.
- The mechanics changed again when glancing blows were introduced, on September 5, 2012. Critical hits that become automatic hits become non-critical hits. Confusing? Yeah.
- Prior to May 22, 2013, the skill Moxious Maneuver allowed using Moxie to determine hit chance regardless of weapon.
