My Dm says we only get 1 hour for lunch :/ but my wizard party member took cat nap spell for the parties short rest features. Worth mentioning he also gains spells up to his wizard level once per day on a short rest which should be accounted for if you are doing a total count. Wizards are the spell mentors we never knew we needed. My patron is low key jealous of my reliance on the wizard and we are currently in a rough patch of our relationship 😆. I sense a spell slot therapy session coming soon 🤣

Thank you so much!

True. Warlocks only have 2 spell slots at those levels. BUT! Those spells slots are recovered after every short rest. So if your party takes 2 short rests in a day, you'll be able to use 6 spell slots. Plus - warlocks always cast their spells at the highest level possible for their level. So at 9th level, you're casting all of your spells as 5th level spells. Plus - warlocks get invocations, some of which allow you to cast another spell once per day, and some of which are always on and can be used an infinite amount per day. Plus you get Mystic Arcanum which let's you cast a 6th, 7th, 8th, and eventually 9th level spell once each per day. 

So, let's do some math. Let's compare a 20th level warlock to a 20th level wizard. A 20th level warlock has 4 spell slots per short rest. At 2 short rests per day you're casting 12 spells, all at 5th level, plus one spell each of levels 6, 7, 8, and 9. That's a total output of 90 spell levels worth of spells. Wizards, with spell slots of 4 3 3 3 3 2 2 1 1, have a total output of 89 spell levels worth of spells. So really, it's pretty even. Sure, there are other variables. But when you factor in the warlock's invocations, they are a very effective class. 

Warlocks simply have to budget their spell use more than other classes. Your general attack will be to spam eldritch blast (with or without shouting that in a Texan accent). Or maybe a weapon attack if you're Pact of the Blade. Your spells are only there to make things interesting. They're the tricks up your sleeve, not your bread and butter. 

I hope this helps. Have fun!

You don't shout "Eldritch blast" you shout "Voodoo gun"

If you take fiend you can have access to wall as fire. If you take meta magic feat then you can quicken it, then eldritch blast them back into the wall if you take the incantation. You don’t even have to have meta magic, just takes another turn. You can also push them of a cliff or into another area of effect spell. With your limited spell slots you really want to focus on concentration spells anyway. So maybe pick up war caster and resilient (con) instead of meta magic, though sorloks are always an option!

 And this is considering they don’t use Eldrich Master and regain all their spell slots…

so okay that’s nuts. At 20th level, this is not a full caster, this is a fuller caster.
