From Diablo Wiki
Maghda is the leader of the Coven, aligned with Belial in Diablo III. She is a key figure in the early game story, and appears in numerous in-game cinematics, usually to taunt the player through the quests. Her key moment comes mid-way through Act One, when she kills Deckard Cain and kidnaps Tyrael.
This plot twist, handing off the death of iconic game character Deckard Cain to a newly-invented NPC most fans referred to as "that butterfly witch" was a very unpopular development, and generated a great deal of fan complaints.
 Boss Abilities
Maghda is a rather passive boss, favoring summoning minions and firing off moths from the moths on her shoulders over getting her own hands dirty, unlike her master, Belial. Magdha has a limited amount of abilities:
- Forcefield: At intervals, Maghda will cast a forcefield on herself, becoming invulnerable until the player deals with her thralls that she summons. Maghda is able to cast Moth Dust while invulnerable.
- Summoning Ritual: Once her forcefield goes up, Maghda will summon three to four berserker thralls to attack the player. The thralls must be killed before her force field goes down.
- Punish/Moth Dust: Similar to the Locust Swarm ability on the Witch Doctor, the moths on Maghda's shoulders will excrete a blue-green cloud of killer insects to attack the player. "Moth Dust" is the ability when she does it at range, and it is a slow-moving projectile. "Punish" is when the cloud is at her feet, in melee range, doing AoE damage.
- Teleport - This ability is precisely what would be expected, identical to the teleport spell found on the Wizard.
