You can pick the "Magic initiate feat: warlock" to get "Armor of Agathys" and some other cantrips of your choice (even eldritch blast) and go full wizard with a full spell growth if you are not using the warlock features.
Ed: Scratch that, you cannot heighten the spell "Armor of Agathys" when using this feat, so it would be cast always at Lvl-1 and that is not very useful.

If not, you can consider picking 2 levels of Warlock to get "Armor of shadows" because that allows you to use INFINITE castings of the abjuration spell "Mage armor" so you can replenish your Ward every turn (but honestly, that is going a little overboard =D )

It also works with any other multiclass build.
