I'm really wondering what is wrong with mostly using your spells? Shouldn't you have some impressive wizzy twink gear that will crank your CR through the roof? Do you get the apprentice robe again (assuming you destroyed the bound old one)?

Yes, screaming of bleed should work just fine. I'm wondering why your wizzy can't do some wizarding. This isn't the pre-spell-pass era when carnifex was prefered (even though just about anything else was better on low-strength arcanes).
