I just saw Chad say in another thread that +EB gloves add to eldritch blast.
After doing a few blasts with and without I could not really see what was different.
I do not understand how blasts works in combination with equipped daggers as a daggerspell mage. Both daggers and gloves are +4.
Everything unequiped:

2nd blast is only with daggers equipped
3rd with both gloves and daggers
4th only with the gloves.

Looking at the image it seems that the +4 daggers give me a +1 to my attack and with only the +4 gloves it gives me +0 to my attack.
Is there a calculation that I am missing?
