When your in the group with another wizard or sorcerer, what spells can be used at the same time? I play in a static group and will be playing a multiclass wizard with a pure wizard for a couple months before we TR. Basically, I'll be the lower level (non pure) wizard. I don't want to overwrite anything our main wizard casts.

From what I understand, spells don't stack even if cast by two different people. For example, if they cast firewall and then I cast a firewall in the same area, only my firewall will work.

I will be the only one casting Death Aura and Acid Rain and I believe they stack with anything other than themselves.

So, which spells stack well for two wizards working together?

Thank You!
