Hero Points/Skills

Hey guys, just got the game a few days ago and I don’t understand the skills or hero points. I figured out how to spend my hero points, but I can’t apply the skill I leveled up, the game seems to choose what skills I use. Can anyone tell me how to assign my skills? Also , what are talents and how do I get them?

Thanks in advance, I’ll keep playing in the meantime.

Skills and talents are attached to items. An axe has certain skills, a sword would have different ones. Look at your items and you will see them.
