If we end up with a TPK, I may use Return of the Lizard King to start them off, then segueing into TOA. It looks like a better option than the AL starter for Tier 1 characters, and since I don't run an official AL table, I have that flexibility.
Wait, Return of the Lizard King isn't AL-legal, is it?
As did I!Edit: Missed that the OP was running an 'AL style' game without being 'AL legal'.
If I lied and said it was, would you buy it? ;-)
Well, the good news is that as of today, all of the Guild Adept adventures, including Return of the Lizard King, as AL legal. For the products that have new rules features like races, classes, and magic items, those rules features are only legal with special campaign documentation. But the adventure parts of them are AL-legal. So have at it!
