I luckily do not need too many spells that are usable this way, since I was thinking that by using "Eldritch Smite" invocation it increases the usefulness of my spell slots, even while raging. Second, what is the list for all those kinds of spells.

So I have two main questions, first if these kind of prepare an effect beforehand without concentration spells do indeed work while raging, because I couldn't find confirmation of if it does. Example, blink or spiritual weapon being cast BEFORE you rage, still being in effect after you rage. This cuts out concentration spell and direct use spells, so I was thinking of using spells that prepare something beforehand, before going into the Rage. Biggest problem is the "If you are able to cast spells, you can't cast them or concentrate on them while raging". There are many problems mixing the two classes, such as locks getting skills to use charisma instead of strength, but rage only getting bonus damage when using strength. So I am currently theorycrafting a lv20 barbarian warlock, which probably already has made half of the people reading this disgusted by the idea.
