Has anyone worked with the Warlock (Binder)

[Sean Abel]

Flavor text" Warlocks manipulate arcane power, as wizards do, but their conduit to that power is vastly different. For a warlock, it?s as much about who you know as what you know?and in effect, the two are the same.
    All warlocks gain access to their power by entering into a pact with some force or entity in which that power rests. In return for their continuing loyalty and service to the source of their power, warlocks become more adept at their craft, and the abilities they bring to the battlefield grow more lethal.
    The type of warlock you can create with this book is the binder."
its from Heros of Shadows (Published in Heroes of Shadow, page(s) 67.) powers are in the program [as always] but a few class features are missing:
Class features: Level 1 Binder Daily Power, Level 1 Pact Encounter Power, Pact Boon (Binder), Shadow Claws, Shadow Twist [Hybrid only gets this if they take binder], Shadow Walk.
