Megamastyx (tier 9) are large, slow, dinosaur-like creatures that dwell in Daemonheim. Their skin is sought after for making excellent Ranged armour.
Players can obtain hides from Megamastyx in one of two ways. Members can choose to trap the Megamastyx with level 80 Hunter, and successfully trapping a Megamastyx yields 673 Hunter experience. In order to trap the Megamastyx, a player must create a bovimastyx trap with the Fletching skill by using a knife (in the inventory or tool belt) on branches. The higher the tier of the branches used to create the trap, the more likely the creature will successfully be caught and killed in the trap. Hunting the creatures successfully will yield between three and seven Megamastyx hides. If the trap fails, the Megamastyx will wave its head at the side of the trap with enough force to dismantle and destroy the trap beyond repair, and another bovimastyx trap will need to be created in order to attempt to trap the creature again.
A second option for members without the required Hunter level is to kill the creature through combat. Unfortunately, this method yields one hide at the most, mainly due to the fact that the skin is damaged through combat. In addition, the use of combat to kill these creatures also yields no Hunter experience, so teams that have the option to trap the creature often do so rather than fighting it. Since the Megamastyx hide is for members only, free-to-play players who kill it will get nothing but big bones. Since all of the Bovimastyx have high health, members who can use Soul Split can use these to regain health.
