Yeah... from what I've seen, an EK from level 1-6 casts shield, sometimes absorb element. The "magic" comes from having a familiar and a few cantrips. At level 7 it opens up a bit, but I feel that should have occurred earlier, for many campaigns that's past 2/3 of the way...The thing about Shield on an EK is it is very strong. It's like stunning fist/paladin smite/hunters mark/hex for their respective classes. It tends to use up your consumable resource, leaving little left over to do anything else. It also tends to channel the EK into the role of tank.
What tends to be overlooked is spell slots are a transferable resource, and EKs benefit more than most from the newer feats, races and backgrounds added to the game.
