This [SE question][1] describes the process for submitting adventures from conventions to Adventurers League to become certified “legal” CCC-AL adventures. 

Adventurers League generally restricts the commonality of treasure in an effort to keep it rare and special. For example, generally Tier 1 adventures will see uncommon magical items. 

What are the general guidelines *or precedent* for how many magical items are appropriate for the length of an adventure and what commonality (i.e. common, uncommon, rare, very rare, legendary) is appropriate for potentially AL “legal” adventures?
