      You can obtain Phantasm Core by defeating the King of Heroes boss, also known as Gilgamesh, on Boss Island. This boss is the only source of the item, so you need to repeat fights multiple times to get lucky with the drop.

      First, you need to travel to Boss Island using the portal system. After reaching the island, you should interact with the summoning NPC near the spawn crystal. Selecting Gilgamesh will let you spawn the boss based on your available resources.

      You need to deal at least 10% damage during the fight to qualify for rewards. The drop rate stays around 0.5% to 0.7%, so multiple runs are required before you see results.

      How to Use Phantasm Core in Sailor Piece

      You will use Phantasm Core mainly for unlocking high-end fighting styles and progression systems. This item becomes essential when you move into late-game builds and want stronger abilities.

      The most important use is unlocking the King of Heroes (Gilgamesh) Fighting Style. This build focuses on strong area damage and fast clearing speed, making it one of the best options for farming and combat.

      You can also use Phantasm Core for Ascension upgrades and crafting special items like the Babylon Key. Because of these uses, collecting more than one core helps you progress further without delays.

      UsageRequirement
      King of Heroes Fighting Style1 Phantasm Core + rare materials + currency
      Ascension Progression2 Phantasm Cores + additional items
      Special CraftingUsed in items like Babylon Key

      Best Tips & Tricks for Farming Phantasm Core

      You should avoid farming solo for long periods since the drop rate is very low. Teaming up with other players helps you defeat the boss faster and repeat runs more efficiently.

      Using high-damage builds will speed up each fight and ensure you consistently meet the 10% damage requirement. Faster clears mean more attempts, which improves your chances over time.

      Server hopping is another useful strategy. You can switch servers after each run to avoid waiting for respawns. This keeps your farming loop active and saves a lot of time.
