I need some help with my Warlock. We're getting a chance to retrain before we pick Paragon Paths, and I can't figure out what I want. In addition my current build feels rather unfocused, with a bunch of different damage types and no real combos or go-to tactics.

My original theory back at level 5 was to be Infernal and use my temp HP to hurt myself without real damage to power Hellish Rebuke, but that plan sort of fell by the wayside and I'm suffering for it.

I can kinda use Eldritch Strike. I like it as a melee option but I'm wondering if I should retrain. Hellish Rebuke doesn't work with Charisma as well, so it's a couple of points behind in attack.

I had Curse of the Black Frost as my Daily 9, but I'm probably going to retrain it to Storm Countess's Kiss.

I'd like to get the benefit of Infernal Prince and my Khyber Shard more often; right now they only work with Hellish Rebuke and Pain to Pleasure. Those are both good things to have it on, so maybe I should be content?
