I want to say that such a battle would be boring to watch or read about. Two people staring at nothing in particular making funny concentration faces until someone's head explodes but Scanners seemed to have made it entertaining.

On a more serious note. Magnus and Lorgar had a brief psykic exchange sometime after Lorgar unlocked/embraced his powers. A brief exchange and nothing serious enough to do more then bruise egos but significant nonetheless as a means to display how much stronger Lorgar became. Both are up there amongst the most powerful psykers in remembered history.

Psykers is such a catch all term, however, and the most powerful psyker may not have anything to do with psyker vs psyker combat due to powers completely unrelated to such activities. I imagine flashy battles would be more likely found in lower level psykers who are content with tossing around fireballs and lightning bolts with a sense of power that's provincial at best. Meanwhile a psychic juggernaut is busy plotting the course of a race with the foresight of millenia.

In addition to the ones in the Ravenor series, it occurs to me that the Soul Drinkers series is likely to have some psyker on psyker combat as well. I believe the main character is the chapter's chief librarian, so it stands to reason he'd fight at least ONE other psyker somewhere in the series.

I'm actually starting to believe that few (if any) writers are willing to do a psyker-on-psyker duel...

It may just be that no one's ever found a way to make it exciting without it being overpowered...

... truth be told, I'm not remembering a dramatic showdown between psykers in the Omnibus. Maybe there's been one since then, but
