Nice build. Look great, and easy to understand everything. Tips are very helpful for new players.
Just one question: You put Quicken Spell on level 1 feat slot, and then you use it to cast False life spell. On level 1 you get on first lifer only 50 SP (OFC after lots of TR and Reaper you have much more). It is worth it?
I mean, why not Maximize meta, take Consume, and kill any big threat from range fast and easy (champs, bosses). You still can cast False life, just a little slower but lower on SP cost.
Did you try Human with Maximize and Empower from level 1? Then route: Consume (1lvl), Feigned Healt (1 or 3lvl), Stricken (2lvl), Cone(3 lvl), Utterdark Blast (4 lvl).
I think this is my favorite low level Warlock - you can kill everything solo without any Hire.
