If I create a hero from a level 2 class it is a level 2 hero. I would then get to either select a new hero talent or increase a characteristic increasing the point value as described. Later under the advancement section it states that if I take an additional talent it will increase the level of by hero (in the example a lvl 2 would go up to lvl 3). Further on it also states, "Hero Talents are not considered Class Traits, but a Hero can only have a number of Hero Talents equal to their level. If the hero starts at level 2 and 1 talent would it not take 2 additional talents to level up, or 3 if they chose the characteristic increase? Is my understanding of Hero Level correct?
Currently, I've been avoiding making any heroes due to not fully understanding the rule, which has caused the other players to avoid making heroes as well.
