Help me build the perfect Sims 4 Werewolf pack!

This reminded me a bit of the game Skyrim where when first starting out as a werewolf you could change at inconvenient times due to the Hircine curse, but once the curse was lifted you could change at will/during the full moon based on a ring they wore.

Not that I expect they'd include cursed/uncursed jewelry, but it was an interesting concept of not being able to "control the beast" at first.
