Jace sat in his room at The Hammered Anvil, the Dawnfire Blade resting on the table before him. He admired the sword's craftsmanship, but his thoughts kept returning to its flaw. The Heat Vulnerability could be a significant drawback in prolonged battles. However, he had an ace up his sleeve: his ability to manipulate reality.
Closing his eyes, Jace focused on the blade, feeling the magic coursing through it. He visualized the flaw, the heat building up within the metal, and willed it to dissipate. Slowly, he began to weave a new enchantment into the sword, one that would not only eliminate the vulnerability but enhance its capabilities.
As he concentrated, the blade shimmered, its runes glowing brighter. He envisioned the sword gaining a morphing ability, allowing it to switch between different forms and abilities at will. The Dawnfire Blade would no longer be just a sword; it would be a versatile weapon capable of adapting to any situation.
