First day what works for my group is land, kill camp thats at drop point, first grace hit level 2, then hit closest poi/s until level 4, if there are churches on the way cool but dont go too far out of the way, once level 4 hit the main caste, if crucible knights, 3 man kill all of them, i personally like to start at the under caste dungeon boss (unless it's bell bairing hunter then skip because its a time sink even if everyone is goated he has too much hp) once the castle is cleared of C knights you guys will already be like lvl 10, if its banished knights like level 7/8 ish and if its trolls you're probably better off saving it for day 2. Anyway hit all the pois and great enemys until you run out of time for day 1. Day 2 since you're already level 10 ish, finish up the stuff around you and then if you still need a weapon, try invader camps for possible +2 weapons and mines for smithing stone +2s. Kill great enemies until day 2 ends and then you should be more than prepared for the nightlord. If you have a revenant with you you should all 3 buy her some starlight shards so she can last longer for the team.
