Inspired by what I saw in "Dragon Age" series, I have a main quest of the story line have the character "dream" into the astral plane where they have several fights towards an unfolding that will provide them with some additional information.
I want to give them some kind of reward which can't be items (after all they are dreaming). I'm already giving them XP if they pull through it but I wanted to give them something else. I was inspired by Dragon Age's pillars which give you an increase of +1 to one of your ability scores.
Is that (+1 to one desired ability score) too much of a reward (making the characters too powerful to early) or is it ok? If it is too much, what are ways that I can reward my players that are not strictly "XP" or "Magic items / treasure" that still feel good to them.
Background: High Epic Fantasy (Epic campaign, the fate of the world is on your hands stuff).
Current character level. 3
Party Size. 3
