Really depends, if Russia have enough artillery for it, then yes, Adviivka would fall, as the Ukrainian hard focus is on Tokmak. The issue here is, whether or not if Russia have enough artillery to take Adviivka, because they loses at least 5 BTG from the attack 2 weeks ago, they wouldn't do that frontal assault if they can spare those Artillery on Adviivka.
Couple to the fact that it's most likely Russian offensive in Adviivka is more or less a diversion (similar to what they did with Kupiansk in August) to keep Ukrainian force off balance, the Russian can't push a lot of resources into Adviivka.
on another news. Ukraine have broke though Bakhmut southern Railway line 2 weeks ago according to ISW, and now Bakhmut is now considered being in contest once again.
Heavy fighting continues in the Bakhmut sector near the railroad there, Illya Yevlash, head of the press service of the Eastern Grouping of the Ukrainian Armed Forces, said during the national telethon program on Oct. 5.

Which mean Russia had lost the only major progress for the first 11 months in 2023......And Ukrainian force are right now at around 22km from Tokmak........There are a lot more for Russian to worry about than trying to take Adviivka.
