Born to a mutant father, imbued with sorcerous potential by a demon trapped in Wundagore Mountain, and raised by her adoptive gypsy parents, Wanda Maximoff's life was full of intrigue long before she became aware of her powers.Marvel Source
The Scarlet Witch began her career fighting the X-Men as a member of her father Magneto's Brotherhood of Evil Mutants.
But she became disillusioned with villainy, instead joining the Avengers after several of that team's founding members left.
As both a mutant and a sorceress, Wanda's reality-altering powers and devastating hex bolts make her a formidable opponent.
You can use Ruinous Tempest + her flying ability to tab most of the minions in Limbo and get lots of xp.
You can also help your group on fresh spawning new waves with Chaos Tempest by staying right in the middle and doing tons of damage to the new wave minions and also kick them away from you and all of your ranged friends.
This is alos the point were Wicked Wand of Watoomb comes into play or shines the most.
Relying on the high damage output of Chaos Tempest and the 40% invulnerable chance of 2 Wicked Wands this almost makes you unkillable on small waves and
is in my opinion and essential part of this build.
You will need some practice but trust me it is a lot of fun and it works.
