How do you gain more experience in the game?

[Leith]

That's precisely the problem! My followers are lagging behind and since there are few monsters that yield good experience, I don'y see how they will keep up. What is worse is that I should have invested my skill points in the 'training' perk early on. Well, I will not do this mistake again on my second run of the game. Forget about the elixir of wisdom! What about the random encounters ? What about the Ruler's attacking parties? See, they have messed up. Although I am still having fun, this game is inferior to KO2 in many ways.
