Summoner question!

Relic +1 first. Magic damage is worth about 7 int per 1 damage. Second best item would be AF+1 Body, but requires a good deal of non-DL items to make up for the lost accuracy, so don't get it too quickly.

This.
Make sure you are prepared to take the -34 acc hit from losing the DL cowl after you +1 your weapon and get a body. Crit > Det for us.
