Spellcasters don't yet have +1 magic wands/staves in EA, so they lag behind in accuracy a bit here.
I believe someone said to me that +1 for spellcasting dont exist in DnD ...
But maybe i remember it wrong.
Anyway, spellcasters actually do have items that gives them +1 for spell hit chance ... they are items that produce lightning charges.
Wand of the war mage +1 to +3 increases the accuracy of ranged spell attacks. These range from uncommon to very rare.
Staff of the woodlands increases druid's spell attacks and DC's by +2. Staff of power and Staff of the magi both do the same for arcane casters. As you'd imagine these are all highly prized rare to legendary staves. I recall seeing some other items too.
That lightning charge staff only affects damage, not accuracy. Nice, as bonuses to spell damage are hard to come by.
[Edit] Forgot Rod of the pact keeper for warlocks. A powered up class specific 'wand of the warmage' that boosts accuracy and DC's.
