[TFS 1.2+] Give item on level advance

Someone asked me on Discord about script that gives configurable rewards on level advance.
It’s onAdvance event. Rewards are easy configurable and can be limited by vocations and level.

local rookVocations = { 0 }
local sorcererVocations = { 1, 5 }
local druidVocations = { 2, 6 }
local paladinVocations = { 3, 7 }
local knightVocations = { 4, 8 }
local mainVocations = { 1, 2, 3, 4, 5, 6, 7, 8 }
local allVocations = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }

local rewardsConfig = {
    -- 2cc and Magic Sword for every 20 level on main
    {
        level = 20,
        vocations = mainVocations,
        storage = 25100,
        items = {
            { 2160, 2 },
            { 2400, 1 },
        }
    },
    -- wand of inferno for 33 sorc
    {
        level = 33,
        vocations = sorcererVocations,
        storage = 25101,
        items = {
            { 2187, 1 },
        }
    }
}

function onAdvance(player, skill, oldLevel, newLevel)
    if skill ~= SKILL_LEVEL then
        return true
    end

    for i1, rewardConfig in pairs(rewardsConfig) do
        if newLevel == rewardConfig.level then
            if table.contains(rewardConfig.vocations, player:getVocation():getId()) then
                if player:getStorageValue(rewardConfig.storage) < 1 then
                    player:setStorageValue(rewardConfig.storage, os.time())
                    for i2, item in pairs(rewardConfig.items) do
                        player:addItem(item[1], item[2])
                    end
                    player:getPosition():sendMagicEffect(CONST_ME_CRAPS)
                    player:sendTextMessage(MESSAGE_INFO_DESCR, "You received reward for getting " .. rewardConfig.level .. " level.")
                end
            end
        end
    end

    return true
end
