Attributes

Arx Fatalis has four base attributes:

Name	Shorthand	Alias	Affected Skills
Strength	Str		Object knowledge (0.5), Close combat (2), Projectile (1)

The raw attribute values without any modifiers are known as raw_<attribute>.

Absolute Item-based Attribute modifications

Equipped items can add or remove attribute points:

modabs_<attribute> = ∑<item>[ modabs(<item>, <attribute>) ]

Relative Item-based Attribute modifications

Alternatively, equipped items can also add or remove a percentage of the attribute points:

modrel(<item>, <attribute>) = modpercent(<item>, <attribute>) / 100
modrel_<attribute> = ∑<item>[ modrel(<item>, <attribute>) ] * ( raw_<attribute> + modabs_<attribute> )

Spell-based Attribute modifications

Curse/bless spells subtract/add one point per caster level for all attributes. Other spells don't modify attributes.

modspell(<attribute>, Curse,   <caster_level>) = -1 * <caster_level>
modspell(<attribute>, Bless,   <caster_level>) = 1 * <caster_level>
modspell(<attribute>, <spell>, <caster_level>) = 0

modspell_<attribute> = ∑<spell>,<caster_level>[ modspell(<attribute>, <spell>, <caster_level>) ]

Full Attributes

full_<attribute> = max(0, raw_<attribute> + modabs_<attribute> + modrel_<attribute> + modspell_<attribute> + cheats)
