How to deal with strong PD?

[VedalkenBear]

Ah. That probably means that you are fighting against Man. IIRC, almost all of Man's PD is Slingers. What I would do is see if you can forge/procure a Staff of Storms. If you can, then you can 'shut down' his missile troops, use Storm Power on all of your Air mages (IIRC, MA TC should get some Air picks on their CMs), and cut loose with the Lightning, which is effective against heavily-armored troops like Knights.

Alternatively, if you have the Air magic to do it (say, on a Pretender), Wrathful Skies would also work. Hope this helps.
