I had not originally mentioned it, but addressing it now sort of falls under the fact it telegraphs her actions rather harshly. The impending feel it creates would be, to varying degrees based on the experiences of each person, a rather obvious tell that they were about to be dealing with a rather tall psyker with a large power weapon, and considering the reflexes of the majority of the high tier folks, could get her in a world of trouble.

As for the low tiers, it would give Vala a chance to set up a last ditch point blank shot or flee, Ansgar to drop explosives and throw himself out the nearest window, or Herold to possibly land the first blow, as ineffective as it could be. Something I had not considered in his favor would be the interaction between the shock maul's, well, shock and the field produced by the Refractor and Rosarius. If the shock could disable the field, he could potentially bring Adrianne down before she had a proper chance to react from her teleport, with a maul and shield combo of blows. If it were a faster effect, unlike what I recall seeing in the past, it would be almost a surefire way to take the first spot.
