Where can we check a guide about maps and monster lcoation?
Since we are pre-renewal, you can look at ratemyserver.
If you want to look the information in-game, simply type @mi <monster/mob ID>
Also, you can use @whereis <monster/mob ID> command to see the location of the mobs
To add-up, you can use @whodrops
or use the map at the upper right of the game, it even give you navigation, on how to go on that mob spot
