Pre-battle settings
If you don't already have a sworn ally enter a province and request for one. If a merchant is in town purchase reinforcements as well! You can boost your bond with two characters this way. *Note you will also increase your bond with every member of the Jin faction by using this method. I maxed out my bond with all Jin characters by grinding this stage.
Equip the fastest horse you have, preferably the Red hare. To get the Red hare you must complete the Battle for Supremacy stage.
Equip a powerful weapon with the Skill point and Congeniality seals. Purchase the extra skill point for each character under the skill tree to get an additional +2 skill points.
------
Select the stage Conflict at Xuchang on Beginner. Start by heading west and defeating the lone officer. Then go straight to the enemy commander in the far north. Step foot into the camp to lure the officers to the middle of the map. Kill the officer to the east, there may be an officer pursuing you while you're inside the camp as well. Once you're finished with them head to the middle of the map (past the two sets of stairs) and round up the enemy officers. Now use your musou and kill the bunch! Finish off any officers that are still alive. Head east and rescue your ally by defeating the last officer in this area. Finally, musou up the big stairs. If you stick around the top of the big stairs, an enemy ambush will appear revealing two more enemy officers. I kind of forgot about that and went to the commander.
This takes about 2 minutes and I net on average ~190 skill points per game. Your officer bond will also increase to 1 full bar.
