I commented it out a few weeks ago or something while under the impression that no one made use of or liked the display. I could put it back in if people want it.
You'd have to set up your parser to look for the phrase specifically. I'm pretty sure I got EQC to pick it up with, i.e., an 'Add to damage' table with trigger text "Zaela empower's %B's attack for %G points of damage."
