"The Decisive Battle of Guandu" is the second and final main mission in Part 6 of Wo Long: Fallen Dynasty. After facing countless enemies, taking down the demon form of both Liu Bei and Lu Bu, and finally learning the identity of the Taoist in Black, the story is now feeling like it is winding down.
With six Battle Flags and seven Marking Flags, "The Decisive Battle of Guandu" is one of Wo Long: Fallen Dynasty's more average-sized stages. Given that it is the final stage of the penultimate chapter, players should prepare to face a considerable challenge. Collecting all flags is one of the best ways to mitigate any danger the mission might bring.
All Battle Flags in 'Decisive Battle of Guandu'
Battle Flag 1
The first Battle Flag is, of course, at the start of the level. This is standard across Wo Long: Fallen Dynasty's many stages.
Battle Flag 2
The second Battle Flag will be very hard to miss, as it is protected by a massive Leader Leishi (Thunder Hogs). As players make their way across the battlefields from the first Battle Flag, they will see a large door in the massive castle wall. The Leishi is directly in front of this large door. Kill it to claim the corrupted flag.
Battle Flag 3



Once the doors are opened behind the second Battle Flag, the player can head up through the giant terracotta soldiers, turning right and go through the white tents. Head up through the house that contains the 'Cao Cao Army Prisoner's Note' tablet. The flag is just out the other side.
Battle Flag 4


From Battle Flag 3, head back down through the building and the white tents. Instead of heading right to go back through the large statues, head left towards a large, circular pit. Battle Flag 4 is found here, and must be cleansed of corruption. The player must defeat a Leader version of Wo Long: Fallen Dynasty' s Aoye boss, the cow demon from an earlier stage. Here, it is simply a mini-boss, but its Leader status makes it quite formidable.
Battle Flag 5


Battle Flag 5 cannot be missed. It is directly outside the door to the first boss area, protected by a Leader version of the giant terracotta soldier.
Battle Flag 6
The Final Battle Flag is found just outside the first boss arena. Head down the path to locate it.
All Marking Flags in 'Decisive Battle of Guandu'
Marking Flag 1



The first Marking Flag can be seen from Battle Flag 1, in an almost direct line above the path. There is a shortcut ladder right next to the flag that can be lowered at the same time. To reach the flag, try to stick to the left side of the path, and following what would seem like the obvious route. When the stakes no longer block the left edge, jump up two levels. Look for the bridge that crosses the long pit that is filled with bodies. The flag will be on the left after crossing. Lower the ladder to create a new shortcut from Battle Flag 1.
Marking Flag 2



From Battle Flag 2, head up the hill to the right. Keep going until the battlefield opens up again, and another Leishi can be seen circling a mud pit. This area is crawling with dangerous enemies, so be careful not to rush in without a plan. Across the field there is a raised area with a white wall for easy access. At the top are two catapults. Take care of the enemies first, then fire both catapults. One of them will smash a wall blocking Marking Flag 2.
Marking Flag 3


After clearing out the village, head into the house straight ahead from the entrance. Drop to the lower path and head in the only possible direction. Jump up the white wall and the third Marking Flag will be directly ahead.
Marking Flag 4


From Battle Flag 4, the player can only exit in a single direction. Head up the hill, then turn to the left to see a series of ledges made from wood and crystal. Hop up to the top and the fourth Marking Flag will be visible.
Marking Flag 5


There is an area just above Battle Flag 3, where a Zhuyan (demon ape) patrols around two small pools of water. Just beyond the water is a small crystal path that leads up and around a small hill. At the top of the hill is the entrance to a room that contains Marking Flag 5. The room also contains a warlock and the backside of a locked door. Be careful going through the door as a Changgui is waiting on the other side.
Marking Flag 6



Turn left at Battle Flag 3 to take on several Shigui (demon mermaids). Once the area is clear, look for the red crystal branch that leads to the roof of a building. Use that to reach the roof, then follow the path up to the roof of the next building. It will appear at first that there is no way to enter the structure, but if the player looks off the edge, they will see a small ledge they can jump down and land on. From that ledge, there is a hole in the wall that leads to the sixth Marking Flag.
Marking Flag 7
Just before the Yuan Shao boss fight, stop at the steps leading to the arena. Turn left and step down onto the stone ground. Now that all flags are complete, prepare to enter the final boss fight at level 20 in Wo Long: Fallen Dynasty's morale and fortitude ranks.
Wo Long: Fallen Dynasty is available on PS4, PS5, Xbox One, Xbox Series X/S, and PC.
