Fizban's first impressions

Also, why in the world doesn't the Drakewarden get Summon Draconic Spirit?

Because no one plays rangers to the point they get 5th level spells :)

It also really feels like a good Warlock spell because of the fantastic upcasting, so it's a shame that they don't get it.

They might add it as a subclass spell for the dragon patron warlock.
