Luv and Bertie's Potion Shop

Luv and Bertie's Potion Shop is a shop in the Skyloft Bazaar in SS undefined.

Features
At Luv and Bertie's Potion Shop, Link can buy Potions that Luv has made (referred to on the Bazaar's map as the Potion Shop) and upgrade them at Bertie's "side business" (referred to on the Bazaar's map as the Infusion Shop). When Link talks to Luv for the first time, she will give him an Empty Bottle.

If Link has a Potion Medal equipped in his Adventure Pouch, the effect(s) of a potion that runs on a timer will last longer.
