In this guide, I will explain the locations of the Berm Leaves, neccesary for the optional quest in which you have to save Hugo's pikkards, whick unlocks the achievement "Savior of Swine"

The first Berm Leave is located in the first zone of the Elderm Mountains, when you go up, you will find a cavity in a wall, the first berm leave is there.

The second Berm Leave is very easy to find, it can be found as you keep ascending, you'll find a bifurcation where you can keep ascending if you go to the right or you can go to the left, where you'll find the second berm leave

This Berm Leave can be found before you exit a cavern when you are ascending, it is behind some ice crystals, which you'll have to break using the fire bracelet.

The last berm leave is found after you defeat the harpies boss, if you keep going to the second zone after it you'll find them hidden in the grass before going up.
