Dynasty weapons.

For now, the most useful staff is the "Staff of Tides," and that's what I voted for! Not only does it provide a FREE pushback of two squares, but it also has a 4-turn ice shield with 225 armor! In the first level of any campaign, it's a golden staff! Right now, I'm playing a mage on the "Haven" faction, but I picked up the "Staff of Oblivion" towards the end of the mission. As I understand it, "oblivion" makes it impossible, for example, for a griffin to fly into the sky, right?
And what is this "Mournful Song"? Is it a staff for humans? I couldn't find a description! I've only just started the second map, so I haven't gotten to it yet!
