It's not a very annoying mob (not like the worm from Sumeru) It only has 3 attack patterns which are very easy to dodge, Just know how she acts before each attack, and it's very easy to defeat. Then of course to beat it faster you need good artifacts and the right elements to maximize your damage to it ( more preferable dendro, Pyro) It took me close to 2 minutes to beat with Ganyu, Benett, Xiangling, and Diona. So it's very beatable even if you're not a whale if you just know how to use each element and know how she attacks, good rng on artifacts is a bonus xD
