Ill post my experience with the energy control sigil here.

I generally feel a bit better since trying to install it a few days ago. Ofcourse this might be something else. I typically dont really react in anyway to these spells so having 0 side effects is to be expected.
I might have asked astra to throw me the dagger, dont know if anything happened.

On a different note someone was claiming an alien race from another galaxy is invading today or the next few days. You can it by typing "alien overlords" in the 4chan search box , not very nice energy as its a gloating type post.
