You must gather NINE squirrels to craft it, dry their tails, which takes long time.
And what you get?
A curio with, TWENTY mental weight and 80 xp cost? Its one of the worst curios when you think of the xp and mental weight costs.
Squirrels are quite early game thing, but with that mental weight no one can study it.
You should at the very least drop its mental weight a lot and maybe xp cost too.

You should look at these numbers, LP/HR/WT and LP/HR/WT/EXP are important during earlygame, nine tails is one of the worst curios in the game, when measured with these numbers.
