Power level of Divine Sorcery Sorcerer
Hello. We're about to start an Odyssey campaign, for which we are all very excited. Looking at the subclasses of the book however, it seems that one subclass in particular seems incredibly over-tuned, namely the Divine Sorcery Sorcerer.
At level 3, you effectively get two free level 1 spell casts and two free level 2 spell casts per short rest, if I understand it correctly. Now, even though you cannot cast those spells with your own slots, these spells are easily applicable to many combat scenario's, so you will likely be using these free castings almost fully every short rest. Assuming even a singular short rest per day, that means you are effectively increasing your spell slot 'pool' from just 4 level 1 slots and 2 level 2 slots, to a whopping 8 level 1 slots and 6 level 2 slots! And as you increase in level, you get higher and higher free castings.
Now on top of getting that insane number of spells to sling right from level 3, you also get a free advantage on concentration saves, because why not.
The higher level features are also top tier to the point of broken: Empowered Magic is a better Twinned Spell, Divine Resistance is straight-up Legendary Resistance on a short rest recharge, and the level 18 feature is also stupidly good.
The entire package just seems incredibly loaded with power to the point where another sorcerer, or full caster, or really any other character will probably feel weak compared to yours. The DM will have to balance encounters completely around your character, not the party as a whole. It just seems to me that in order for a Divine Sorcery Sorcerer to work in a campaign, it needs to be nerfed quite massively.
Am I correct in my assessment of the subclass? Or am I perhaps misreading something? Is it supposed to be overpowered, being effectively demigods?
