Optional - Cave of the Seven Stars

Access the optional Cave of the Seven Stars in Star Ocean: The Last Hope after defeating the Undying Dragon and obtaining the Darkness Ring.

Cave of the Seven Stars: B1

Upon arriving on floor B1, you will find yourself in a room with a floating orb. Explore the rest of the floor to understand its purpose. Be aware that the monsters encountered here, such as the Gust Hornet, Bone Knight, Winged Nightmare, Treant, Crater Peryton, Leonblade, and Guiafairo, represent a significant difficulty increase with higher HP and stats.

The Gust Hornet is particularly dangerous due to its numbers, quick rush gauge fill, and frequent critical hits. It is advisable to avoid them until better prepared, or use Bacchus's _Black Hole Sphere_ Special Art to group them for easier management.

Treasure Chests on this floor contain items like Aquaberries x2, Platinum x1, Bracteate x1, Cane x1, and Stone Fragment x1.

Navigate the maze-like paths to find the final treasure chest in a room at the far south. Entering this room triggers a scene followed by a boss battle.

Boss: Temple Guardian

The Temple Guardian, a mechanical boss, has 958,949 HP and is resistant to Water but weak to Thunder. It attacks with homing missiles, a spread beam from its snout, and Special Arts like _Earthquake_ and _Tail Smash_. _Tail Smash_ is a sweeping attack that can inflict Stun.

A party of three attackers and a healer is recommended. Focus on ranged attacks to avoid _Tail Smash_ and chain your longest Special Arts, utilizing Rush Combos when character Rush Gauges are full.

After defeating the Temple Guardian, collect the Stone Fragment x1 from the Treasure Chest it guarded.

Return to the room with the floating orb. You will see four starburst patterns on the walls. The southeast wall's pattern is unlit. Place the Stone Fragment in the depression on this wall to light it.

Once all four starburst patterns are lit, the seal on the floating orb is released. Examine the orb to be transported to floor B2.

Cave of the Seven Stars: B2

Upon arriving on floor B2, you can use the floating orb to return to floor B1. This floor contains two glowing and two darkened starburst patterns on the walls. You need to find two more Stone Fragments to place in the depressions of the darkened patterns to advance to floor B3.

Treasure Chests on this floor include Ripe Berries x1, Evil Spirit's Bow x1 (Darkness Barrier), Stone Fragment x1, Moonstone x1, Gnomestone x1, and Stone Fragment x1 (Ivy Barrier).

Explore the labyrinthine passages. Head northeast first to find a Treasure Chest, then proceed counter-clockwise to the south side. The chest in the northwest area contains the Evil Spirit's Bow x1, a weapon for Reimi.
