Robes of the Archmage, Grimoire +3, Wand of the Warmage +3
Do they stack?

Yep.
Uses up all three attunement slots though.
As a DM, you can rule any way you like.Let me rephrase that: do you, as a DM, have to let them stack?

+8 to spell attacks, +5 to save DCs on your Wizard spells.
So glad I use the 'Natural 20 passes a save, and a nat 1 fails it' houserule.
