Verunan Pillar of Light is useful, because the Zhonian Sacred Fire is useful too. I fought once online with Henrique and he took Zhon. I was unable to destroy his Death Totem, because of the Sacred Fires and Thirsa's repairing combination. Now that I am thinking of it, when I play with Veruna, I should use Pillar of Light behind Watch Towers, Mortars, Bastions, Lighthouses, Crossbowmen, Ballistas, Musketeers and Centaurs. It would make them more durable.
