How to Get the Ossus Red Mastery Datacron

Quick Travel / Taxi

Republic side, there is a quick travel and taxi on the same map as the entrance to the datacron.

Imperial side, there is the Dead Forest quick travel, but no taxi, if you don’t have the quick travel take the Ossus Canyons Camps speeder and the run north.

Find the Cave

Find the Secret Entrance

Inside the short cave there will be a hidden crack in the wall with some stone steps in it, which you can climb up into. Look for blue mushrooms on the wall for a hint to the path.

Climb the Steep Cave

From there, just start climbing up any way you can.

There’s really only one way to get kinda stuck, and if that happens just back track and go the other way.

Once outside, jump from the mountain to the roof of the ruins.

And get the datacron!
