My Warlock somehow has aquired a Rod of the Pact Keeper and Staff of Power .

Do the +2's to my attack bonus stack?

[Malifice]

Yes.

You get +4 to spell attack rolls with Warlock spells, and +2 to the Save DC of your warlock spells as well.

The RoTPK bonus only applies to Warlock spells, and the staff doesnt add to save DC's.

What about adding the Robe of the Archmagi to that list

Better question: Do you have enough free hands?

Yep. Your warlock save DC can get ridonkulous.

I think my Tiefling looks silly but powerful carrying one in each hand!

Really, that was a thought. I need a holster for them lol.
