The Wuthering Waves 2.6 update has released a new region in Rinascita called Sanguis Plateus. Naturally, you can find several treasure chest spots with four or five Supply Chests. However, many more chests are hidden, located in areas, or locked behind a gimmick that makes them easy to miss. Collecting them will give you a decent amount of Astrites.
This article will cover seven such Supply Chests that might have escaped your attention in Wuthering Waves 2.6.

Chest #2

Teleport to the Resonance Beacon north of the Atlilius Canyon and go to the treasure spot southwest. You will find a Premium Supply Chest there. However, it is actually a chest mimic, and you must defeat it twice to get the real Premium Supply Chest. This will give you 40 Astrites.
Chest #3

Teleport to the Echo Flight Challenge II located west of Sanguis Plateus, and fly southwest towards the westernmost part of the region. Next, rotate the second and fourth bell crab altars such that all the altars are facing the sea. This will give you a Basic Supply Chest, worth five Astrites in Wuthering Waves.
Chest #4

Go to the Tideline Verge Nightmare Nest and then head north to the small island to find an NPC standing in front of a crab statue. Talk to him and go to the other side of the island to collect Shrimp. Once done, return to the NPC and hand over the Shrimps to get a Basic Supply Chest that is worth five Astrites.
Chest #5

Teleport to the southern Resonance Beacon in Asphodel Barrens and go to the waterfall northwest of your location. You will find a Standard Supply Chest inside a hidden space behind the waterfall.
