Melee weapon, requires attunement. The wielder makes 3 attacks per action, each dealing 1000d1000 plasma damage on a hit plus 1000d1000 bonus plasma damage from the active plasma lattice. The hilt cannons fire automatically on each hit and at the start of each round against nearby threats, consuming 8 energy per discharge (50-cell energy magazine, reload action required when depleted). On a critical hit, trigger the plasma shockwave (DEX save DC 17). The Unyielding Core passive grants damage resistance to the attuned wielder and prevents any single damage source from reducing them below 1 HP more than once per encounter. The blade's AI targeting cannot be disabled.
