Okay, now for
getting a heroic ability in the first place... If you make it into the HoF, you'll get a heroic ability. There are common ones which you'll get in most cases, and really rare ones which you only get with a chance of 1 out of 20. The starting value for the heroic ability stat, which I wrote about before, starts at 100 for all the heroic abilities.
The rare ones:
- Awesome Presence
- Battle Bellow
- Undead General (only for a Death or Blood Mage or a nation of some type, my guess is with an affinity for undeads; never for MA Marignon)
- Adept Researcher (only for magic users)
- Third Eye (only for units with exactly two eyes, duh)
- Heroic Stupidity (only for non-mages)
- Legendary Cruelty
The common ones:
- Heroic Strength
- Heroic Battle Prowess
- Lightning Reflexes
- Iron Will
- Valor
- Tough Skin
- Heroic Toughness
- Heroic Quickness
- Heroic Precision (only for units with a ranged weapon or spellcasters)
- Heroic Endurance (my guess is, only for units with something else than a base value of zero enc)
- Unequaled Obesity (my guess is, not for units that need not eat)
- Heroic Agility
Which of these heroic abilities you'll get, once it has been decided if it's going to be a common or rare one, is totally random and it only matters if the unit fulfills the requirements that I wrote in parentheses. Where I am not sure about the actual check, I wrote my guess what the check is about that is being performed.
I'm a little surprised that magic users can't get heroic stupidity. I could swear that I got it before, but maybe I'm thinking of getting the "mute" affliction instead, or this got changed in some previous patch.
