Crystal Solvent is a valuable resource in Wuthering Waves, an action RPG game known for its immersive world and dynamic combat system. This rare item plays a crucial role in managing the game's energy system, better known as Waveplates, allowing players to participate in various resource-rewarding activities without being constrained by natural energy regeneration limits. Much like Fragile Resin in Genshin Impact, Crystal Solvent provides a way for players to gain 60 Waveplates instantly, and as such enabling players to grind materials from Overlord bosses, Tacet Fields, and more, while also helping players level up their Union level faster.
