Rage skills levelling - how does it work?

[Zechnophobe]

Rage experience generation is based on three primary factors:

The power of the spell used.

The damage it deals at the time you use it.

The size of your army compared to the opponents.

Each time you use a rage ability, you get a flat amount of experience based on how it has been leveled up. More upgraded skills generate more experience. It then gains an additional flat amount of experience based on how much damage it deals AT THAT TIME. Rage abilities that deal damage after their are cast do not gain this bonus (but also tend to get more base experience).

Lastly, if your army is much larger than the targets, you will gain less experience. This is true for all uses of rage, except for the very first one of each fight. That one will always gain full experience independant of army size.
