Large Hydro slimes and Hydro abyss mages have a hydro aura that will summon bubbles around your character to entrap you. Often, you get affected by the Hydro aura, and your skill cooldown will increase after use, making the combat difficult. Whenever I'm playing this domain, I use catalyst characters like Klee, Ningguang, or Lisa to not depend on elemental abilities to easily break shields. If you are entrapped in a bubble, you can press the space bar to get out of the bubble and continue the combat. Another team composition I like to run is full Cryo composition with Rosaria, Chongyun, Kaeya, and Sucrose to freeze the enemies. Chongyun's elemental skill helps you infuse your normal attacks with Cryo, and you can constantly keep enemies frozen. I don't like to run a combination of Hydro and Electro because I can get stun-locked in the process, and Abyss mage will not let me go of bubbles.
