Hexblade help

So, I'm a hexblade lvl6, but I'm missing my lower spell slots for things like shield for example. and I want to dip to pick them, I know that a charisma based would be great but my stats are insane (18wis 19int 20cha) and we already have a paladin and a sorcerer, so i start to think outside the box.

Maybe some forge cleric? wildfire druid for teleports? can you guys give me some suggestions?!
