We are writing a CCC Convention Adventure for Adventurers League that grants animals as part of the treasure blocks. Adventurers League generally restricts the frequency and commonality of the magic items that are distributed in adventures, but we can find no guidelines for mounts or pets, nor can we find any precedents in 1st-party adventures.
The Tomb of Annihilation campaign season introduces the island of Chult which is populated by dinosaurs that the inhabitants regularly ride and Al’miraj which run wild and are referred in the MM as potential familiars for wizards.
How does one write a CCC Adventure that is AL legal that involves distributing trained mounts or exotic pets, such as Al’miraj, pseudodragons, pegasi, or even more mundane mounts like trained warhorses?
Though these creatures don’t appear to count as permanent magical items, certainly some creature allies could be just as powerful as one.
What are the AL Tier guidelines around awarding or offering creatures for sale as treasure?
We understand that Fai Chen’s Fantastic Faire has had exotic mounts available for trade for magical items. Details of the rarity of items (uncommon, rare etc.) accepted for different classes of pets and mounts would likely suffice as precedent if there are no other guidelines.
