Gardhaven Castle Enemies

Gardhaven Castle is populated by Dux Aldrich’s remaining forces. Key enemies include:

• Imperial Elites: Simple foes that attack twice. They have a 5% chance to drop Runeshard of Fire/Light/Darkness 5. If fought with a bow, they have a chance to drop Runeshard of Earth 5. Equipping the Super Lucky Badge can aid in farming these Runeshards.
• Ogres: Similar to those encountered previously.
• Mine Orbs: Can pose a threat with their Self-Destruct ability, dealing around 200+ HP damage. Prioritize these enemies.
• Modified Specimen H_008 and Synthetic Specimen R_0901 and H_008: These enemies can stun with regular attacks and often act first.
• Arch-Demon: Encountered in the Library. Three of these can use Crimson Nova, dealing heavy fire damage to the entire party. Using the Friendship Hero Combo with Seign can be effective if Nowa has high attack power.

Obtaining the Blue Lens

To progress through Gardhaven Castle, you need to find the Red and Blue Lenses to unlock colored doors. The Blue Lens is found on the 2F.

1. Head east from the main hall, then north, and enter the second entrance on the left to find stairs leading to 2F.
2. This section of 2F is separate. Follow the path to the end and find a chest containing a Rune of Medical Studies (increases healing item effect by 50%).
3. Return to your right and check the statue to claim the Blue Lens.
4. Return to 1F and use the Blue Lens on the blue door in the north main hallway. Search the chest inside for a Sacred Helmet.
5. Return to the Rune Lens door, save, and prepare to find the Red Lens.

Obtaining the Red Lens

The Red Lens is located on the western side of the castle.

1. From the main hall, head west, then north. Enter the blue door on your right and loot the chest for a Holy Circlet.
2. Continue north, ignore the next path, and open the door on the right with the Blue Lens. Inside, find a chest with a Blessed Shield.
3. Leave this area and go north to find a chest in the corner containing a Rune of Supersonic Speed.
4. Return to the path you skipped and use the Blue Lens to access the main part of 2F.
5. Head west, south to the bottom, then east to find a chest with a Rune of the Knight’s Path (reduces attack by 50% for defensive boost).
6. Return to the skipped path and head into it.
