This was previously posted on the Starfall Prophecy beta sub-forum, but I know some players don't go there, and I'm not sure what is going to happen to the topics there now that the expansion is launching. Given that, I am reposting my guide here!
I have posted a quick guide to Planar Fragments over at The Ghar Station. You can view it here:
Please leave feedback here, and let me know if there is anything to add and/or tweak! Hopefully I covered the important basics and provided useful recommendations at the end of the article.
The Ghar Station is a Rift datamining blog, so expect many of the other posts on the site to contain spoilers!
EDIT: updated link to the new ghar station site!
