Orthen is a large dig site spanning several areas across the Island of Anachronia. It can be Excavated starting at level 90, after you obtain an invitation, and its last Hotspots can be accessed at level 120. There are a total of 5 different Cache types, 8 Research locations, and 8 Mysteries.

The sections below will give you details concerning each section of the dig site.

Base Camp

The Base Camp area has no Hotspots, Cache, Research, or Mysteries. The Archaeologist workbench and a Material storage container can be found just outside the Town Hall. To access the Hotspots, Cache, Research, and Mysteries associated with Orthen for the first time, you will need to walk to the sites with or without using the Agility course. Once you have unlocked the teleports to the specific locations, you can use the Orthen teleportation device near the Dragonkin statue at the center of the Base Camp. The sections of this guide have been separated into sections based upon these teleport locations. Note that to unlock and use the teleportation ability, you must first and foremost speak to Mr. Mordaut then activate the Base Camp device by clicking on it.

Rex Skeleton - Osseous

Similar to the Pylon battery received at Kharid-et, while Excavating at the Orthen site you will occasionally obtain Rex skeleton fragments. These fragments are used to complete the Rex skeleton, Osseous, just South West of Mr. Mordaut. Note that the fragments cannot be banked. When fully built, Osseous will roar and activate a boost for 66 minutes wherein you will experience the following boosts while on Anachronia:

+25% Experience

• Agility course
• Archaeology
• Fishing
• Hunting
  • Big Game Hunter
  • Butterfly (Ruby harvest & Black warlock)
  • Golden warbler
  • Grenwall
  • Jadinko
  • Pawya
  • Yellow salamander
• Woodcutting (Overgrown idols)

+10% Drop Rate

• Big Game Hunter
• Codex page
• Slayer Monsters

Each fragment accounts for 0.001% completion (100,000 total needed to activate the buff). When helping to complete the skeleton, will earn you some experience (scaled to your Archaeology level) for each fragment. Contributing 10-99 fragments will earn you an extra 10% experience and contributing 100-1,000 will earn you 20% more - up to 1,000 fragments (1% restoration) can be added at one time. Note that the skeleton in all worlds share completion. The completion percentage can be checked by Right clicking it and choosing "Check restoration".

Potions

With the addition of Orthen, 5 new potions were added to the game. Similar to the Combination Potions, these recipes require that you discover a recipe before you can make them. Unlike Combination Potions, these recipes are obtained in 4 pieces while excavating specific Hotspots - fragments are always received in order from 1 to 4. These new potions include:

To restore the recipes, simply have at least 1 of all 4 fragments for a specific recipe in your inventory. Click any of them to open the crafting interface. Here you will be able to choose the potion recipe you wish to make (if you have multiple in your inventory). Note that you only need 1 Crafting to combine the pieces and will earn 10 Crafting experience for doing so.

Recipe fragment pieces are not tradeable, however, the completed recipes are.
