Just completed defeating the emperor. I stayed targeted on the Emperor, ignored the clones, and interrupted his force blasts. Got him down on my 2nd try.

Here is my Jedi Sentinel, Strumwulf on Voss, after acquiring a new lightsaber. https://images-wixmp-ed30a86b8c4ca887773594c2.wixmp.com/f/a804c6c9-10ac-485a-a4e6-a456ff2b5c0d/d4ql8gx-574ffc86-a530-4993-939e-48aca8125596.jpg?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1cm46YXBwOjdlMGQxODg5ODIyNjQzNzNhNWYwZDQxNWVhMGQyNmUwIiwiaXNzIjoidXJuOmFwcDo3ZTBkMTg4OTgyMjY0MzczYTVmMGQ0MTVlYTBkMjZlMCIsIm9iaiI6W1t7InBhdGgiOiJcL2ZcL2E4MDRjNmM5LTEwYWMtNDg1YS1hNGU2LWE0NTZmZjJiNWMwZFwvZDRxbDhneC01NzRmZmM4Ni1hNTMwLTQ5OTMtOTM5ZS00OGFjYTgxMjU1OTYuanBnIn1dXSwiYXVkIjpbInVybjpzZXJ2aWNlOmZpbGUuZG93bmxvYWQiXX0.nf5S-02L9_31HztKlpxtw0E2MuVFz0tQe1brkMLPgh4

Is there any chance to see what my Jedi Knight was up to while under the Emperor's control? Maybe something like the messages from Bengall Morr.

Open your skill window for Artifice, and check the individual items you can make for what materials are needed. For example, crystals will require a color crystal, a power crystal, and maybe an artifact, and some 4th material. Archaelogy will get you most of your crystals (color and power), artificats, and some special materials. Treasure hunting will give you the special gems needed for some schematics, as well as money, equipment and schematics. Hope this helps.
