My parter and I just started playing Wizard
101 and we love it. We're both around level
20. She is a storm/death wizard, and I am life. I
haven't picked a second school yet, but I will
probably go balance.
So far we have beaten every boss and sunken
city, just us two. Will we be able to do the whole
game like this? Can two wizards alone defeat the
hardest boss (Malistaire?)
Hi Boris! First off, great combo. If I were you (a storm and life combo is exactly what I did for my kids' characters), I would go with storm for my secondary and snag the balance traps and blades from Niles in Krok. Storm has a ton of traps in their main line that you can help the storm wizard lay down the pain with. Once the storm wizard gets tempest, you pretty much win the game with that combo. It's a ridiculously awesome spell.
Now for your question, you can take that duo all the way to Malistaire's door, and then you will be stuck. You need three people to open Malistaire's door. Each person stands by a crystal and you all click at the same time to unlock the door to Malistaire. That's the only time you really "need" a third person for your combo.
**UPDATE** Or do you! My long time reader SDW noted that you can use the Mark Your Location feature to quickly teleport one of your duo to the third crystal in time to open the door. Thanks for the tip, SDW!!! **UPDATE**
Now, there are certain fights that will be difficult to do with just two people . . . I'm thinking stormfather in grizzleheim in particular . . . and if they ever release the harder difficulty boss fights as an optional battle again, those will be tough or impossible to do with just two players. But that's just it, those fights are optional.
Other than that, I think you'll be golden! :-)
