BattleMessageProxy.OnReceive('pk_message', function(proxy, message)
    local damage, creature = string.match(message, 'You lose (%d+) %a+ due to an attack by (.+).')
    if Creature.New(creature):isPlayer() and not Creature.New(creature):isPartyMember() then
        while (not Self.isManaShielded()) do
            Self.Say("utamo vita")
            wait(300, 500)
        end
        os.exit()
    end
end)

Added party member checker & it makes sure you casted utamo vita

I love you
