I played as the Academy faction on a large map: in 4 months and 3 weeks, I managed to gather 60 Rakshasas, taking into account losses of 7 units. If I had Kubera instead of Fahim, it would be: +3 to the initiative of the entire army – a pretty significant bonus, not even considering the +3 to attack bonus, which is quite unnoticeable compared to that. However, this special ability is completely useless on dueling maps. It would be better to have requirements like: 10, 40, 70, 100..., which seems better than 20, 40, 60, 80.... I also have an idea for a special ability (for the League or Inferno): before a battle, the hero forces the opponent to "forget" their spells. If the hero's level is higher, the opponent forgets all spells. If the hero's level is equal to or lower than the opponent's, the opponent forgets 1 spell from each school. After the battle, the opponent "remembers" the spells. Maybe it could be simplified somehow, but the idea should remain.
Riva is completely white on the map, and if you look at her in the hero menu, the elephant is painted in a white square with black borders.
