Thanks.Rod of the pact keeper for warlocks.
So barring this exception there really isn't anything comparable to a +1 weapon for spellcasters in this edition.
(Since spells with saves are much more common and thus important than spells with attack rolls, I mean. I am fully aware the war mage wand is mechanically just that. I just think getting a +1 to attacks isn't "the +1" a spellcaster wants... Not yet, in any case. If and when there are lots more spells-with-attacks this may change)
