Class features are not written with the optional multiclassing in mind. But... this abomination can do whatever it wants.When you find a wizard spell of 1st level or higher, you can add it to your spellbook if it is of a spell level you can prepare and if you can spare the time to decipher and copy it.
At least in my copy, it specifies that you can copy a spell into your book as long as it is of a level you can prepare.
You cannot prepare level 3 wizard spells as a level 2 wizard.
You do have the spell slots for upcasting though
It's a 9th level character, off-hand I don't see what 3rd level spell is going to break it.
On the other hand, this sort of mix-and-match level tomfoolery is why I don't like 5E's multiclassing.
Someone's likely been casting that on them since 5th level.Haste.

Action Surge and casting? Just don't use a Bonus Action spell (or two concentration spells), and you're good.Perhaps but they can cast it themselves now. We'll at level 15 I was thinking maybe it was 9 but I misread it.
I'm just not 100% certain how it works with action surge.
