I also love doubling down on my casters with Magic Initiate. For Wizard that would let you start with 5 cantrips and have another ritual spell know for your book and get one free casting of it per day. I'd recommend Detect Magic. You can then cast it once per long rest as a standard action without burning a spell slot, and it's in your spellbook so if you need it again later you can ritual cast it.
For a setting like Avernus, I would go for conjurer. Its ability for gear on demand, easy reuse porting and such seems to me a good fit for a somewhat post-apoc setting.Whats up guys!
For the last few days I've been wondering/asking you guys about which Class I should roll for a new campaign (Probably Descent into Avernus, no spoilers btw XD).
I've been all over the place, considering rolling Rogue, Warlock, Sorcerer... and I finally decided to roll Wizard. Cause thats a Class that I've always been interested about, but I thought I didnt have experience enough to play (played 5 unfinished campaigns, somewhere around 40 sessions)... but screw it, Im going for it! haha
Now that I made up my mind, I'd like your opinion about Subclasses, Races, Backgrounds and General Tips that you think its important.
So far from what I read about, I liked Divination and Evocation for Subclasses. The Races probably High Elf, Half-elf and Variant Human. Backgrounds couldnt settle on these.
So what do you guys recommend and what tips can you give to a first time Wizard?
