If you send me a PM I might help you with the errors, if you still have them but I can't ensure that I can help because I don't have a environment setup.
 
Update for TFS 1.2

Note: Attack speed, extra attack are not as straightforward to implement so they aren't yet. Charges can be easily implemented but isn't yet!


STEP 1: When an item is created we assign it random variations, this is done in the item.cpp class.

In the item.cpp class, inside the constructor with signature Item::Item(const uint16_t _type, uint16_t _count /*= 0*/)

Below
Code: 
if (it.isFluidContainer() || it.isSplash()) {
        setFluidType(_count);
    } else if (it.stackable) {
        if (_count != 0) {
            setItemCount(_count);
        } else if (it.charges != 0) {
            setItemCount(it.charges);
        }
    } else if (it.charges != 0) {
        if (_count != 0) {
            setCharges(_count);
        } else {
            setCharges(it.charges);
        }
    }

Add
Code: 
//NEW - RANDOM
    if (it.armorRndMin > -1 && it.armorRndMax > it.armorRndMin)
        setIntAttr(ITEM_ATTRIBUTE_ARMOR, it.armorRndMin + rand() % (it.armorRndMax + 1 - it.armorRndMin));
    if (it.defenseRndMin > -1 && it.defenseRndMax > it.defenseRndMin)
        setIntAttr(ITEM_ATTRIBUTE_DEFENSE, it.defenseRndMin + rand() % (it.defenseRndMax + 1 - it.defenseRndMin));
    if (it.extraDefenseRndMin > -1 && it.extraDefenseRndMax > it.extraDefenseRndMin)
        if (it.extraDefenseChance == -1 || (it.extraDefenseChance >= rand() % 101))
            setIntAttr(ITEM_ATTRIBUTE_EXTRADEFENSE, it.extraDefenseRndMin + rand() % (it.extraDefenseRndMax + 1 - it.extraDefenseRndMin));
    if (it.attackRndMin > -1 && it.attackRndMax > it.attackRndMin)
        setIntAttr(ITEM_ATTRIBUTE_ATTACK, it.attackRndMin + rand() % (it.attackRndMax - it.attackRndMin));
    //NEW - RANDOM

STEP 2
Next we need variables to store these random variation values, this is done in the items.h file inside the ItemType class.

Inside items.h
Below
Code: 
int32_t runeMagLevel;
int32_t runeLevel;

Add
Code: 
//NEW - RANDOM
        int32_t armorRndMin, armorRndMax, defenseRndMin, defenseRndMax, extraDefenseRndMin, extraDefenseRndMax, attackRndMin, attackRndMax, extraAttackRndMin,
            extraAttackRndMax, chargesRndMin, chargesRndMax, attackSpeedRndMin, attackSpeedRndMax;
        int32_t extraAttackChance, extraDefenseChance, attackSpeedChance;
        //NEW - RANDOM


STEP 3: Now we need to assign these variables when we load item definitions from the items.xml file. The loading happens in the items.cpp class.

Inside items.cpp

below
Code: 
} else if (tmpStrValue == "armor") {
            it.armor = pugi::cast<int32_t>(valueAttribute.value());
Add
Code: 
pugi::xml_attribute tmp = attributeNode.attribute("random_min");
            if (tmp) {
                it.armorRndMin = pugi::cast<int32_t>(tmp.value());
                tmp = attributeNode.attribute("random_max");
                if (tmp)
                    it.armorRndMax = pugi::cast<int32_t>(tmp.value());
            }

Still in items.cpp Below
Code: 
        } else if (tmpStrValue == "defense") {
            it.defense = pugi::cast<int32_t>(valueAttribute.value());

Add
Code: 
pugi::xml_attribute tmp = attributeNode.attribute("random_min");
            if (tmp) {
                it.defenseRndMin = pugi::cast<int32_t>(tmp.value());
                tmp = attributeNode.attribute("random_max");
                if (tmp)
                    it.defenseRndMax = pugi::cast<int32_t>(tmp.value());
            }

Still in items.cpp Below
Code: 
        } else if (tmpStrValue == "extradef") {
            it.extraDefense = pugi::cast<int32_t>(valueAttribute.value());


Add
Code: 
pugi::xml_attribute tmp = attributeNode.attribute("chance");
            if (tmp) {
                it.extraDefenseChance = pugi::cast<int32_t>(tmp.value());
                tmp = attributeNode.attribute("random_min");
                if (tmp) {
                    it.extraDefenseRndMin = pugi::cast<int32_t>(tmp.value());
                    tmp = attributeNode.attribute("random_max");
                    if (tmp)
                        it.extraDefenseRndMax = pugi::cast<int32_t>(tmp.value());
                }
            }

Still in items.cpp Below
Code: 
        } else if (tmpStrValue == "attack") {
            it.attack = pugi::cast<int32_t>(valueAttribute.value());


Add
Code: 
                pugi::xml_attribute tmp = attributeNode.attribute("random_min");
                if (tmp) {
                    it.attackRndMin= pugi::cast<int32_t>(tmp.value());
                    tmp = attributeNode.attribute("random_max");
                    if (tmp)
                        it.attackRndMax= pugi::cast<int32_t>(tmp.value());
                }

We still define the variations in the items.xml file the same as before:
ex:
Code: 
<item id="2463" article="a" name="plate armor">
        <attribute key="weight" value="12000" />
        <attribute key="armor" value="10" random_min="9" random_max="11" />
        <attribute key="slotType" value="body" />
</item>

Hi!
This feature is freaking awesome. I was wondering if it'd be possible to add more stats, like fire absorb dmg...etc
 
how to make something like ???

<attribute key="skillaxe" random_min="5" random_max="8" />

and

<attribute key="maxhealthpercent" random_min="5" random_max="8" />


<attribute key="speed" random_min="5" random_max="8" />

0.4
