Well only tomb and skull dont banish, unless some1 can prove it to me. Madray and mong are not Bosses anymore becuz they do not have seals. In fact they are downgraded to minibosses. Minibosses consist of for example:firehand, punishers,the golem etc. They are just regular monsters which spawn very little and have high HP and are more advanced than regular monsters. However Bosses have a higher ranking than Minibosses :P. Right now only one thing that can beat the rank of Bosses is like u need many ppl to take that boss down. Something like MStory's Pink Been or something, or maybe the bosses of the Harkon statue.
Dragon nest FTW, Nexon can eat my crap ><
