The Easiest Way To Deal With Andrius (Genshin Impact) 

I do got C3 on my Tighnari due to accidental pulls of him, but I assume you can do doubt deal with Andrius the same way at C0. Dendro Essential Oil plus Adeptus' Temptation, and I found using them allows Andrius to be taken down quickly with the team lineup I use for him.
It's a good quick way if you need this boss for older characters you wanna level up.
