lol no, that thing was a force of nature. Someone with a few tamer accounts could probably solo it but expect to lose some pets.
That being said I was in the same area the rest of the night and didn't see it again, so it seems like someone got it. I am new and technique is not my strength (yet) Maybe someone with more finesse could get a good strategy working.
Dealt with a mystic white wyrm the other day. Used 3 tamers and took down one of my dragons. But thats because I haven't triple boxed in some time so i was pretty sloppy with my macros. Mystics for the most part I have noticed are kind of glass cannons. I'll watch my pets health pretty closely and before I know it, the mystics health is pretty low and almost dead.
i believe mystic monsters have the same barding difficulty as their normal monster equivalent so actually u can keep provoking monsters to attack it to wear it down
The barding difficulty of a monster is an additive calculation of their skill and stats. Below is an image some mystic mobs I did on test server over 2 months ago before the shame mine update. These stats are near what you will see with the mystic monsters on live server. I used 2 dragons to test the proposed templates of each mystic, didn't want to make them too easy.
