During the quest "A Brush of Seafoam and Crimson" with Mileusina Mamere, players may encounter difficulties and not understand what to do with the strange red ore and how to resonate with the prism. In this guide, you will get an answer to your question!

How to Use Prism Resonance and Ore in Genshin Impact

Actually, it's not as complicated as it seems at first glance - you just need to hit the smaller red ore with a regular attack and direct its beams at the larger prism. It's important to position yourself correctly so that the wave hits the target directly. Below are screenshots to help you adjust the position correctly!

Approaching the next marker, you'll notice a strange, hollow-looking ore. To activate it, you need to approach the adjacent ore and direct the wave towards the hollow one - this way it will charge, and you'll be able to strike two adjacent prisms with it.

Then, finish off the remaining prisms - there should be no more difficulties. Good luck!
