MostDamage Reward

[paweleq2000]

Hello, i have problem, this script give reward to player who last hit monster.
Can someone change this script to give reward for player with most damage?

local config = {
    points = 5, -- how many points winner get?
    }

    local names = {'earth stone', 'icy stone', 'fire stone', 'wind stone'}

function onDeath(cid, corpse, deathList)
    if (isInArray(names, getCreatureName(cid):lower())) then
        --local mostdmg = deathList[2] ~= nil and deathList[2] or deathList[1]
        local mostdmg = isPlayer(deathList[1]) and deathList[1] or (deathList[2] ~= nil and deathList[2])
        if isPlayer(mostdmg) then
       
            db.executeQuery("UPDATE `accounts` SET `premium_points` = `premium_points` +" .. config.points .. " WHERE `name` = '".. getAccountByName(getCreatureName(mostdmg)) .."';")
            doPlayerSendTextMessage(mostdmg, 22, "You have killed " .. getCreatureName(cid) .. ". You won 5 points to sms shop.")
            db.executeQuery("INSERT INTO metin_wins (name, reward, reward_id, stone, date) VALUES ('" .. getCreatureName(mostdmg) .. "', '5 points', '2', '" .. getCreatureName(cid) .. "', " .. os.time() .. ")")
       
        else
            doBroadcastMessage("No one has destroyed the stone")
        end
    end
    return TRUE
end
