Questions about the gameplay of Heroes 6.

1. Did you learn about the Siege Master's special ability from the "Battle Journal"?
2. Is this second special ability of the Siege Master perhaps a BUG?
3. If you only increase the General magic power (raising Earth magic for this purpose doesn't seem very effective for level 10), what damage can a single stack deal instead of 16?
4. As I understand it, does this Siege Master ability work more effectively for a Mage than for a Warrior?
5. There is a rumor that "Finding the Way" is bugged. Have you checked if this is true? Are you leveling up "Finding the Way"?

1. Yes.
2. It looks like a bug.
3. Check the manual; all the formulas are described there. The base damage is 41 (when the hero is level 30). For a level 1 hero, the damage is 4. And it is multiplied by the ratio of the Earth magic power and the unit's magic defense. Earth magic also has regeneration and stone skin. So, in total, there is a reason to level it up.
4. Yes, the Mage's magic power increases faster.
5. It seems to be a bug; it doesn't work. I didn't check it specifically; I just estimated. Here is an artifact - a saddle - it seems to work, removing the penalty...
