ItemPropertyACBonusVsRace

From NWN2Wiki

// Returns Item property AC bonus vs. Racial group.  You need to specify
// the racial group constant(IP_CONST_RACIALTYPE_*) and the AC bonus.  The AC
// bonus should be an integer between 1 and 20.  The modifier type depends
// on the item it is being applied to.
itemproperty ItemPropertyACBonusVsRace(int nRace, int nACBonus);

Note: It is not clear why IP_CONST_RACIALTYPE_* is used instead of RACIAL_TYPE_* which contains the same values
