Appearance: The Sentinel of Everlasting Flame is a majestic longsword with a blade crafted from a unique crimson metal that glows with an inner fire. The blade is straight and sharp, with intricate flame-like designs etched into its surface that flicker with a golden light. The hilt is wrapped in black leather, adorned with red and orange gemstones that resemble burning embers. The crossguard is shaped like outstretched wings, and the pommel features a blazing ruby, constantly pulsating with a warm, fiery glow.

Lore: Forged by the god of fire, the Sentinel of Everlasting Flame is one of ten legendary weapons created to bind or release the Usurper, a being of immense power. The sword embodies the essence of eternal flame, channeling the destructive force and purifying nature of fire. It serves as a key in the complex ritual that maintains the Usurper's imprisonment, representing the fiery resolve needed to protect the world from chaos. In the wrong hands, the Sentinel could unleash unparalleled devastation, as it holds the power to unlock the Usurper's prison.

Powers and Abilities:

1. Blazing Aura: The longsword emits an aura of intense heat. Creatures within 15 feet of the wielder suffer 15 fire damage at the start of their turn if they are not immune to fire damage. The wielder can choose to suppress this aura.

2. Inferno Strike: When you hit a creature with the Sentinel of Everlasting Flame, the target takes an additional 4d8 fire damage. This damage bypasses resistance to fire damage.

3. Flame Burst: Once per long rest, the wielder can use an action to unleash a burst of fire in a 30-foot radius around them. All creatures in the area must make a Dexterity saving throw (DC 20) or take 12d8 fire damage and be knocked prone. A successful save halves the damage and prevents the knockdown effect.

4. Raging Inferno: The wielder can cast Fireball (DC 18) once per day without expending a spell slot. When cast this way, the damage is maximized, and creatures that fail the saving throw are also set ablaze, taking 4d6 fire damage at the start of their next turn.

5. Eternal Flame: The wielder is immune to fire damage and can breathe in environments filled with smoke or toxic fumes, including volcanic regions and infernos, without harm. The longsword also prevents the wielder from being magically burned or scarred.

Curse: The Sentinel of Everlasting Flame is bound to its wielder and cannot be discarded or willingly given away. The weapon has a fiery will and slowly influences the wielder to embrace the destructive nature of fire. Over time, the wielder may become increasingly wrathful, impulsive, and prone to destructive tendencies, reflecting the weapon's fiery spirit.

Sentience: The longsword is sentient, with an Intelligence of 16, a Wisdom of 18, and a Charisma of 14. It communicates telepathically with its wielder, understanding Common, Primordial, and Ignan. The Sentinel is passionate and impulsive, always seeking to unleash its fiery power and reveling in destruction.

Destruction: The Sentinel of Everlasting Flame cannot be destroyed by conventional means. It can only be destroyed when all sources of fire in the multiverse are extinguished, an almost unimaginable feat that would require the elimination of every flame and heat source across all planes of existence. Until then, the Sentinel remains an indestructible artifact, forever bound to the essence of fire.

Proficiency with a Longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
