Affinity, also known as base hit chance, is a multiplier in the hit chance calculations that contributes largely to the accuracy of an attack. It is a number which normally ranges between 0 and 100 and is effectively a percentage modifier to attack accuracy; the higher the affinity, the higher the hit chance of the attack is.

 

Monsters and players have affinity values for each combat style. Monster affinities are fixed, but player affinities are determined by worn equipment, represented in the Loadout interface by style bonus. Monster affinities also affect the hit chance of summoned familiars.

 

Monster affinity

The affinities of a monster are relatively simple. By default, they have the following affinities:

• 90, against their explicit weakness

• 65, against their explicit weakness's style

• 55, against the style they are neutral to

• 45, against the style they are strong against
   

For example, a monster weak to fire spells would have an affinity of 90 for fire spells; 65 for other magic spells; 55 for melee; and 45 for ranged.

 

Certain monsters have their affinities hard coded; e.g., many boss monsters have an affinity for every style set to 40.

 

When a monster has a weakness listed as being an entire style, this generally means that the highest affinity (90) is unused, meaning the tool tip is representative of which style affinity is the highest. Monsters with no weakness also do not use the highest affinity - their other affinities are not necessarily all equal or neutral, either.

 

Player affinity and style bonus

All armour has a related affinity, which determines how accurate attacks done against it in each style are. This is represented as style bonus in the equipment stats menu, as a positive number for stronger defence (that style has a lower hit chance), a negative number for weaker defence (that style has a higher hit chance), or zero (that style has a neither boosted nor reduced hit chance).

 

Armour has affinity 65 to the style it is weak to, 55 to the same style, and 45 to the style it is strong to; hybrid armour has 55 affinity to all styles.
