Elite Skills showing up at the Hero Skill Trainer.

Well, one at least. I was looking at skills available in the Sunspear Great Hall, when I decided to look at Assassin skills (for whatever reason). I was greeted with the following:


As can be seen, the elite, Assault Enchantments, is showing up on the list. It is important to note that the skill wasn't "taught" to me when I clicked on it, nor did it use up a hero skill point. Has anyone else seen this sort of thing?

Yes indeed. Tried it and also couldn't get it so had to cap from the boss. Wiki has had this information for a while.

As far as I know, it's the only elite that a Hero Skill Trainer has.
