    if creature:getCondition(CONDITION_EXHAUST_HEAL) then
        creature:sendTextMessage(MESSAGE_STATUS_SMALL, Game.getReturnMessage(RETURNVALUE_YOUAREEXHAUSTED))
            return false
                end
                    creature:addCondition(exhaust)
                addEvent(function() item:transform(31173) print('item removed') end,0)
            addEvent(function() item:transform(31093) print('item removed') end, cooldownTime)
    return combat:execute(creature, var)
    end

What I'm doing is adding a cooldown and transforming the rune to another to display that it's on cooldown. The problem is it only works while in a backpack. How would I go about making it work outside of a backpack? Also is there a way to force use or far use on an item without changing the .dat?

If the item that you are transforming gets removed your server will crash. Because it will refer to null pointer. You should get the item again in addEvent.
