How to remove (Unlearnt) Hero Skills?

i want the hero to be able to choose 1 skill, and after that, all other choosable skills must be removed AND the red cross must be removed... how to do this?

i tried to find an action to do this, but i haven't found one.

ive also been thinking of replacing the hero with another hero without those spells and adding the right abilities etc, but thats time spending, cuz i need to change a lot of triggers then too.. (like 50)

does anyone have an idea?
thanks in advanced

Use Level of Ability for Unit in Integer Comparison.

you cant remove the hero abilities like that.
use a spellbook ability, put dummy "learn skill" abilities inside it, add the corresponding skill to the hero and remove the spellbook when he uses one of them.

lol thats a good idea! but i already done that thanks anyway
