Yep. And they don't get EB as a cantrip.
Good idea.Hexblade gets to be its own class, with hit dice and equipment proficiencies appropriate for a melee class from level one without accidentally giving those things to casty/blasty warlocks,
It's a nice kit. I saw a lot of Thief/Magic Users in OD&D and AD&D.
As far as fiction goes, the AT is a far more capable adventurer, with some spell casting ability rogue 'live by your wits" themes than cugel was in Vance's Dying Earth stories, and it touches a bit on Grey Mouser having been originally a magician's apprentice which leads to the original thief has some magical talents bit in Greyhawk.
At table, they are great to have in the party. Very flexible and each one I've seen at play has been a unique character.
