Mira Eamon is the wife of the Blacksmith, Haedrig Eamon. She is slowly turning into a shambling undead horror in the Cellar of the Damned in Tristram, Act I when the player is tasked with killing her for the quest A Shattered Crown.
She's a bit like the Wretched Mothers in that she throws up but she doesn't produce any zombies from it, perhaps because she's only recently 'turned'. She has a poison projectile but even with that she's a very easy fight.
