How to Find Basically Purple Teyvat Products

The easiest way to collect all the shots is to photograph the Lavender Melon in Inazuma.

Location 1

Teleport to the Konda Village. The first melon will be near the teleport, in a basket behind one of the houses.

Walk a bit forward from where you found the first melon and photograph the fruits from the tree.

Location 2

Walk from the teleport closer to the coast. Photograph the tree with melons.

Location 3

Climb up the shore to the last tree.
