Below is a walkthrough of the Oswald’s Hideout main story event in Rune Factory 5.
Client: Oswald
Location: Bandit King’s Old Base
Objective: Rescue Oswald’s left behind friend
To start this event, Terry will tell you about an anonymous message left for you requesting that you head to the Belpha Ruins at midnight. After doing so, Oswald will show up and ask you to rescue one of his friend’s left behind at his base. You’ll then want to rest and set out the next day. Make your way to the Bandit King’s Old Base, which can be found in the southeastern part of the Phoros Woodlands.
Bandit King’s Old Base 1F
Work your way through the first floor, defeating the enemies along the way. Keep your eye out for walls with cracks on them as you can break them using your mining hammer to reveal hidden areas. When you reach the middle of the floor, there will be a blue gate blocking your path forward. Head west to reach a room filled with mimics. Defeat them then flip the blue switch to cause the gate to lower. You’ll then need to return to the room with the blue gate and head east. This will bring you to a long room filled with traps. Run to the other end of the room, dodging the traps, to press the green switch. This will allow you to head forward into the next room. In the next room, there will be 3 switches near the entrance. Pressing the right switch causes an enemy to spawn. Pressing the middle one causes a boulder to fall down on you dealing damage. Pressing the left one lowers the gate blocking the way forward. Head past the gate and use the save point. Head to the next room to trigger a dialog event leading to a boss fight. Defeat the Geyser Bear then head to the next floor.
Bandit King’s Old Base 2F
Work your way through the second floor, defeating enemies as you go. After clearing the room with all of the bulls, you’ll come to a room with 4 switches. You’ll want to press the left (northern) switch to open the gate forward. Follow the path then use the save point. Head south to trigger a dialog event leading to the second boss fight. A good strategy for this fight is to stay behind the boss and attack it from behind. Defeat the Mysterious Lizard then head south into the next area. If you take the right path heading west, you’ll come to a room with a green switch at the end. Flip the switch to cause the green walls in the room to lower revealing enemies. You’ll have to defeat them all in order to leave this room. If you head to the eastern room, there will be more traps protecting the blue switch. Avoid them to activate the switch. Once both switches have been activated, you’ll be able to progress to the next floor.
Bandit King’s Old Base 3F
Once on this floor, use the save point then head forward into the big open room to trigger a dialog event leading the third boss fight against Dragon Golem. For this boss, stay on the sides of it. Also, watch out for the boulders that it flings. After you defeat it, a quick dialog event triggers. Head south to the next room where you’ll find Oswald’s friend. When you regain control of your character, the event completes!
