Added how-to-obtain, uses, storage info, and tips

A massive power core found within Abyss creatures. Its energy output is so immense that no ordinary means can control it. The core serves as the lifeblood for higher entities that have condensed Abyssal energy, though it carries the risk of going berserk.

Named Power Cores like Power Core - Spire of Defiance are rare drops from Abyss creatures and can also be found during Abyss puzzle encounters throughout Pywel. They appear as glowing blue crystalline formations and must be collected using Axiom Force; you cannot simply pick them up like standard loot.
The Spire of Defiance drops from the Crimson Nightmare boss. After the boss is defeated, a cutscene plays and you cannot pick it up immediately. The core will appear in the Howling Hill Provisioner's recovery tab. Make sure you have the Kuku Pot unlocked (from the Chapter 4 Kiln Repair quest) before defeating the Crimson Nightmare, as a known bug can prevent the core from appearing in your Kuku Pot if it was not unlocked at the time of the drop.
Used as a crafting material for high-tier Kuku equipment and research projects at the Kilnden Workshop.
Power Cores are stored in the Kuku Iron Pot, a special container unlocked during Chapter 4 by completing the Kiln Repair quest at the Kilnden Workshop west of Hernand. The Kuku Pot holds up to 230 Power Cores and is accessed through your inventory using Axiom Force.
If you drop a Power Core in the field and lose track of it, check the Provisioner at your camp. Lost Power Cores can be repurchased for a small Silver fee.
Power Cores cannot be stored in regular inventory slots. They must go into the Kuku Pot.
Use the "Discard" option in the Kuku Pot inventory to place a Power Core on the ground when needed for puzzles or crafting stations.
Always unlock the Kuku Pot before fighting bosses that drop named Power Cores. Without it, the cores may end up in a limbo state that requires story progression to resolve.
Named Power Cores are much rarer than generic Elemental Cubes. Save them for their specific crafting recipes rather than using them in general research.
Check your Supply Chest and Provisioner recovery tab if a Power Core seems to have disappeared after a boss fight or cutscene.
