Leveling a Paladin and read the tooltip of Judgement that says " Judges the target, dealing (112.5% of Spell power) Holy damage and causing them to take 25% increased damage from your next Holy Power ability"
What is counted as Holy Power Ability? Is it the spenders, Templar’s Verdict and Divine Storm?
Yes, it’s Templar and Divine Storm. Our spenders? Literally everything else except Word of Glory and (if you spec into it) Seraphim, which is a really strong 45 second CD.
