Where do I raise attributes at level-up?
 

Manual says:
Aside from experience the player may raise parameters (they mean attributes) when gaining a leave, visiting certain places etc..

Don't I get a choice of which attributes to raise?
When I level up, is say gained Leadership +20 and that's it. I don't see an option either at the level up screen nor the character screen to increase anything...

I hope I'm just stupid, blind, or something else.. Help mehhh!! :)

On the side note, how do I "Cancel" a spell or dragon ability? Sometimes I want to verify troop's health after I click "Fireball", say, but I can't undo. Cursor stays in "Wand" form and question mark doesn't appear so I can left-click to examine.

After each level you gain runes which you can use for skills in the hero's menu and several of them can increase your attributes.

You should click right mouse button to cancel the spell or dragon ability.
