Break Shields fast in Genshin Impact by using the correct elemental damage. These counters are especially important in the Spiral Abyss.

A Bit More About Hydro Shields

You may have noticed that Hydro Shields are a bit less vulnerable to its elemental counter than other shield types.

Against a Fatui Hydrogunner you can apply Electro (for Electro-Charged) which deals DoT. Eg. spamming Lisa’s Elemental Skill.

Alternatively you could apply Cryo (for Freeze) which gives crowd control and additional Physical Damage.

As for Hydro Abyss Mages from my experience Cryo is the way to go.
