Hi David, you can try bringing ningguang + albedo in first team. Most important thing to remember is the two rangers needs to be killed first (they will spawn at 2 o clock, 10 o clock, 8 o clock and lastly 5 o clock. Once these 8 are dead the next is the giant hilichurls. Avoid fighting near monolith. Use ningguang jade wall to block arrows. (Block the 10 o clock and 5 o clock ones). For the second half you need some form of crowd control or very high damage. I used venti+jean for this if damage is not enough. Focus on cicin and fatui agent first. The treasure hoarders as well but not main priority. (Ignore the fat treasure hoarder with shovel- he does 0 damage to monolith) good luck
11-2 mostly about crowd control and gameplay mechanics, if you can control the mob aggro, you basically won.
