Couldn’t find anything when I searched.
I noticed today that you can get multiple skill points from the commune-type skill challenges and it was easy to repeat.
1. Open the skill challenge’s dialogue.
2. Begin communing with the skill challenge.
3. While channeling to complete the challenge open the skill challenge’s dialogue again. It will have the “commune” option available for selecting.
4. Once the First channel completes, select the commune option again from the dialogue box you opened in step 3 and channel for a second time.
5. Profit??? who knows what you would do with all of those extra skill points anyway.
