So, Elder Mok's Hero Ability,
Watchman's Quick Recovery
Watchman's Unity, with 4 willpower.
Makes... 1 health, 1 stamina and 1 movement point completely free for absolutely everyone starting near you ?
Since Quick Recovery would trigger Elder Mok's Ability, the cost is virtually 0. Quick Recovery then triggers Unity; profit.
Have you found other combo like those ? I do think that Hybrid Classes can open a few like this. I've seen some amazing Mages Hero as Warrior Class. I mean, as long as you don't really want those 3 XP skills, that you would usually get only in the later quests anyway, it just clearly gives you the option to pick in another hero "palette" for your class.
