WoW API < GetSpellCritChance

Returns a players critical hit chance with spells for a certain school.

theCritChance = GetSpellCritChance(school)


school - the spell school to retrieve the crit chance for

  • 1 for Physical
  • 2 for Holy
  • 3 for Fire
  • 4 for Nature
  • 5 for Frost
  • 6 for Shadow
  • 7 for Arcane


An unformatted floating point figure representing the critical hit chance for the specified school.


The following function, called with no arguments, will return the same spell crit value as shown on the Character pane of the default UI. The figure returned is formatted as a floating-point figure out to two decimal places.

function GetRealSpellCrit()

    local holySchool = 2;
    local minCrit = GetSpellCritChance(holySchool);
    local spellCrit;

    this.spellCrit = {};
    this.spellCrit[holySchool] = minCrit;

    for i=(holySchool+1), 7 do

        spellCrit = GetSpellCritChance(i);
        minCrit = min(minCrit, spellCrit);
        this.spellCrit[i] = spellCrit;


    minCrit = format("%.2f%%", minCrit);
    return minCrit;


The above function is essentially a straight copy of the function from the Paper Doll LUA file in the default UI.
