Monsters In game

I've been IG testing out some monsters and tried to think which ones that should be common monsters and which that should be rare etc etc. I've also had in mind that the monsters should fit our shard.

Common Mobs (Nature mobs):

Trolls
Ogres
Imps
Mongbats
Giant Spiders
Gamans
Harpys

Rare and more dangerous mobs:

Dragons
Wyvern
Drakes
Dread Spiders

Evil and very fierce:

Shadow Knight
Moloch

I also want a connection between the monsters and the location where they spawn, that's a must to get it a bit realistic...

I will keep on update this list since there are a load of mobs to choose from. Feel free to add any suggestions!
