Spells and Invocations for my character?

[Sintanan]

What would be the best choice of spells and invocations for a Warlock 4/Sorcerer 1/Eldritch Theurge 10? I'm aware there's a few spells you can't ignore, same with invocations... but with the ability to blend them together, are there any must have spells?

For good spells and invocations, try looking through a Sorcerer Handbook (http://brilliantgameologists.com/boards/index.php?topic=2180.0) and a Warlock Handbook (http://brilliantgameologists.com/boards/index.php?topic=2915.0) first, then come back with any questions you have.

Generally, however, you will want to use a Bard/Sublime Chord instead of a Sorcerer entry, so that you have a chance at both 9th-level spells and Dark Invocations without having to choose.
