I'm reworking some of my older campaigns in Pathfinder 1e and transferring them into Pathfinder 2e. One of the custom items I had in an original dungeon was a supposed "Wand of Wish" that was actually a "Wand of Aberrations"; functionally, it was a 1 charge wand that would apply a random +0 lvl Template onto either the character using it or the character the user indicates (depending on the intent and situation). That being said, I've decided to rework this mechanic into an "Idol of Lamashtu".
The encounter involves a devout Bugbear using one of these items to attain a boon from Lamashtu, the bugbear fighting the party and at least one identical idol for the party to loot. While it'd be easy to just have the idol apply one of Lamashtu's Divine Curses, I think it'd be more interesting and perfectly thematic to give the user a random kind of Lycanthropy (see the bottom of the page); this comes with the added bonus of having a solid item level to calculate treasure with. However, when I look up Lycanthropy between the Bestiary and Archives of Nethys, they never say what level the curse is, such as when they talk about a Curse of Nightmares being Curse 2 and Sellsword's Folly being Curse 9.
All that being said What Level Curse is Lycanthropy? Or better yet, what level would a cursed item that inflicts Lycanthropy be?
