Unlocking New Villagers
When a player's camp manager level increases, villagers are unlocked. Which villager is unlocked is based on that villager's tier and excludes villagers unlocked through Gulliver and Blathers. A player will unlock all the villagers in a lower tier before unlocking higher tier villagers. The last of these villagers is unlocked upon a player reaching level 76.
For example, Beau is a Tier 3 while Stella is Tier 6. This means a player will unlock Beau before Stella.
