Fair enough, forgot about that one.
Star Pact could be CHA or CON, with most later material favoring CHA.
Fey is CHA, Dark is CHA, Sorcerer-King is CHA, Gloom is CHA.
The Hexblade and Binder classes from Heroes of Shadow were CHA based as well.
It's easy to primarily think of Warlock in 4e as a CHA based class with a few CON based builds.
EDIT: Sorcerer-King could be either CHA or CON, only one I've ever seen was CHA, so I forgot.
