This one is in our favor, but it might be playing into other issues with waves. Under the Sea today featured an initial wave of 4 ISO Mutant goons. That went as expected - gathering AP while slowly whittling them down.
The second wave entered with a bunch of weak Doombots. I was using 2* (obviously) Storm, Thor, and Magneto. The Doombots entered, and I fired Thor’s Call the Storm to clear them, planning to stun/KO any incoming characters with Storm’s Wind Storm.
Scarlet Witch came in as expected, but she took a chunk of damage from Thor’s green. She started with about 1300 of her 2700.
