Dew of Repudiation

To obtain a Dew of Repudiation you'll need to find and destroy the Hydro Hypostasis on any World Level. The higher your World Level, the higher your chances of receiving multiple components at once. To receive components you'll need to spend 40 Resin each time you defeat this Boss.

There is no quest requirement to find the Hydro Hypostasis. You can find it on Watatsumi Island. Refer to the image below for its location:

A strange water droplet left behind by the collapse of the Hydro Hypostasis. It has strong rejection properties, and this forms the basis of one of the Hydro Hypostasis’ attack patterns as well. They say that water contains memories and willpower, and that these things can grow when bodies of water meld together. However, the waves conjured by the Hydro Hypostasis are incompatible with the currents that flow above and below ground. Even if it were to flow into the surpassingly pure waters of Petrichor, this drop of water will likely resist assimilation as strongly as mercury.
