Editing Imperium Maledictum (section)

===Psychic Powers===
* While you still need to make WP checks, you now have Psychic Mastery as a skill to make those checks easier (plus whatever specializations you pick there).
** Pushing lets you take a Mastery check with advantage, but now you must take 1d10 additional Warp Charge for it. Fumbling makes you auto-trigger Perils.

* Warp Charges is now a pool of psychic energy that builds with each power you cast, with failures building it up faster and a hard threshold of your Willpower bonus unless you have talents to boost that. Of course, a high Warp Charge lets you boost the damage Force weapons give.
**You can spend an action to roll Mastery in order to purge the excess charges and then make it just trigger random minor spooky phenomena. Let it build up too much and you need to make an emergency Mastery check in order to rein the power in or else spill out the PERILS.

* Alongside the other major disciplines, you can also pick up Minor powers like back in 1E. Even better, You already know Smite as a default power alongside another minor power and a discipline. Taking the Psyker talent again lets you pick other disciplines.
** While discipline powers cost the same as a talent, minor powers are actually a bit cheaper.
