What's your favourite heroic ability?

[GriffinOfBuerrig]

I excpecially lige Strengh, because this skill reaches REALLY epic dimensions(Wraith lord with strenght 50 - Jaaaaaaa!)

[Wish]

I like extra HPs, magic resistance, or defence on my assassins/succubi

quickness is by far my favorite over all, but i never get it on a unit who can make it worthwhile

Hmm, tossup between Heroic Toughness (I currently have that on a Tomb Priest who had 40 HP to begin with! ) and Battle Bellow (I once had that get up to +15 fear - on Angelique d'Armant! Kinda comical actually! )

I always somehow wind up with battle prowess on my artillery mages and super-good researcher on my fightin' dudes. I did once get awesome presence on an air queen, and it was... awesome. Nobody with a morale less than 14 or so could even think of hitting her, and it was early enough in the game that this was still a big deal.

I don't find strength to be that great (although it is better with some of the lifedrain nerf mods). On spellcasters, reinvigoration and precision can be very helpful. Otherwise I mostly agree with the ordering of your list.
