Hit roll is the formula used to determine the success of an attack. Each time an attack is made on an enemy player, an internal calculation will take place to determine if the attack misses or not. The term "hit roll" is a holdover from tabletop role playing games, where dice were rolled to determine if an attack was successful.

How the hit roll is calculated

There are two ratings which are checked when an attack is made, attack and defense. Having more attack rating then the enemy's defense will increase the chance to hit, and having more defense rating than an attacker's attack rating will lower their chances of hitting you. The hit roll will never drop below five percent hit chance, so it is impossible to become invulnerable with high defense.

Defense and Meele attack rating are displayed on the character info screen, while spell hit rating is found when hovering over the spell's cameo.

Attack rating

Attack rating or ATR, is the number given to most offensive abilities that determines the chance to hit successfully. As a player accumulates attack rating, it becomes harder for their attacks to miss. Attack rating can be increased by training spell or weapon focus skills, equipping weapons with specific enchantments, and precise stance. An attack or spell with no hit rating will always hit.

Attack rating can be calculated using the following formulas:

  • Spell Attack Rating = (Dexterity or Strength depending on weapon type / 2) + (Primary Skill * 4) + (Secondary Skill * 2) + (Attack Rating Magical Bonuses on Weapon(s) and Buffs) * (Stance Modifier) * (Special Attack Modifier)

  • Melee/Ranged Attack Rating = (Primary Stat / 2) + (Weapon Skill * 4) + (Weapon Mastery * 3) + (ATR Enchantments) * 1.stance modifier

Defense Rating

Defense rating or DEF, is the opposite of attack rating. It determines one's resilience to any effects that depend on an attack rating for success. As a player accumulates defense rating, it becomes harder for attacks to hit them. Defense can be increased by training armor focus skills, defense enchantments on items, and defensive stance.

Defense can be calculated using the following formula:

  • Defense = ((Dexterity*2) + (Total Armor Defense*(Armor Skill * .03)) + (Shield Armor * (shield skill * .03)) + ((Primary Weapon Skill + Secondary Weapon Skill)/2)) * (1. Stance Modification)
