Dromomastyx are large, slow, dinosaur-like creatures that dwell in all tunnels under Daemonheim. Their skin is sought after for making excellent Ranged armour.
Players can obtain hides from Dromomastyx in one of two ways. Members can choose to trap the Dromomastyx with the Hunter skill. 40 Hunter is required to trap this creature, and successfully trapping a Dromomastyx yields 330 Hunter experience. In order to trap the Dromomastyx, a player must create a Spinebeam trap with the Fletching skill by using a knife on Spinebeam 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 tend to yield between three and seven Dromomastyx hides. If the trap fails, the Dromomastyx will wave its head at the side of the trap with enough force to dismantle and destroy the trap beyond repair, and another Spinebeam trap would need to be created in order to attempt to trap the creature again.
A second option for non-members and members without the required Hunter level is to kill the creature through combat. 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 can have the option to trap the creature often do so rather than fighting it.
