Talk:Hero skill trainer locations

Are these skills here listed from Nightfall skill set only? For example: I noticed that Godaj at Lair of the Forgotten offers more monk's skills - just the rest of them are from older chapters. Rafal 12:34, 14 November 2006 (CST)

What about learning skills you already have?
Most of the skills offered I already have. What happens if I accidentally click a skill I already have? Will I loose a hero skill point anyway? Wouldn't it be better for the Hero Skill trader to hide the skills people already have?
