Best Psychic Powers for a Disciple of Abraxas

By Darth Fanboy, in Rogue Trader

I've got myself the Navis Primer, and one of my favourate bits from it is the Disciple of Abraxas alternate rank. For those who don't know, they're a Mechanicus sub-cult who integrate psy-active xeno tech into themselves in order to gain an esoteric set of abilities (up to three over the alternate rank).

So, I'm looking for some suggestions on interesting powers to use, either as a PC in general terms, or as an oponent.

Personally, I'm liking the Rak'Gol powers Telikinetic Sledge and Reap the Flesh or the Eldar Destructor and Enhance from the same book for antagonist powers.

When I looked over them, the Rak'Gol powers looked pretty attractive to me as well.
