three noobie questions

[rdonj]

1. The ancient master gives experience to whoever enters the site. In case you don't know, units gain experience by existing and taking part in battles in dominions, and the more experience a unit has the higher its stats become.
2. Spells in blue like that are national spells. These are spells that can only be cast by that particular nation, or a small number of nations. You didn't find it in your manual because bogarus was created after the release of the game.
3. Number of effects in that case is the number of units it creates. Call of the wind summons a commander bird and 20 lesser birds to any province you wish.
