Players seeking baby dragon bones often choose to fight their blue counterparts as the possibility of red dragons or wild dogs attacking and the need for a hatchet and 875 coins to gain entry to the area deters many players. There are safe spots for rangers and mages, but players may still be attacked by wild dogs. These monsters, like all dragons, are best attacked using ranged attacks.
