I don't understand the utility of a rune beetle. Maybe i don't be able to use it well I have a very good beetle but if i don't heal it continuously it dies in a while is it right? I often read that many people go against monsters with rune beetles. Is it my fault? What monsters are more weak by the attacks of a rune beetle? I know english not very well and i know that "more weak" is wrong. But i hope that you have understood what i have to know Thanks!
