This was challenging. Many more colorful words come to mind but it’ll stick with “challenging.” But,I’m stubborn and I couldn’t handle seeing those empty sockets in my Legacy datacrons tab.

Ossus Presence Datacron (+5 Presence)

Ossus Red Mastery Datacron (+6 Mastery)

Ossus Endurance Datacron (+2 Endurance)

The +2 endurance datacron is very involved. It includes finding and clicking multiple triggers in different areas of Ossus and you HAVE to do them in a certain order. You also have to make sure you only click ONCE on them. There is nothing in chat that shows if you clicked, no pop up, etc. You just have to make sure you click it only once or you have to start over with this datacron. In addition, the last step of this datacron is a lot of jumping, a lot of platforming, and puzzle solving. Oh and this all happens in the dark. You do get one of those floating flashlights but I turned my settings all the way down and had my pike with its super bright crystal active (attack stance, “z” is my keybind) and that helped a lot. 

Of note, you get the Ood Bnar weapon tuning with the endurance datacron. You only get one, per Legacy. Before you get bummed out about that, all you have to do to put this tuning on other characters is to put it in a Legacy weapon and take it out with the character you want to use it with. 

This is what the tuning looks like (basically a little wood looking vine that coils around part of your weapon). I don’t know what it looks like on other weapons yet but I do like this one. The gif doesn’t do it justice but may at least give you an idea. 

There are a few guides out there, all of them valid but the one I thought was the easiest to follow is this one:

Yay, no more empty sockets!
