Battle with the Demon Dragon 2        

Salathiir, the Demon Dragon, loomed over the battlefield with an aura of malevolence that sent shivers down the spines of even the bravest adventurers. 

Its scales, a fusion of darkness and suffering, glistened ominously as it prepared to unleash its agonizing spells upon the players confronting it.

Salathiir's eyes glowed with an unholy light as it tapped into its formidable spellcasting abilities. Its [Agonizing Spellcasting] was a formidable barrier, and the air crackled with dark energy as it prepared to cast its spells. 

The mere act of resisting its spells inflicted necrotic damage upon those who dared challenge its might.

A sinister energy radiated from Salathiir, creating an [Aura of Suffering] that extended to creatures within 60 feet. 

As the guild approached, they felt the necrotic tendrils of agony seeping into their very essence, causing damage and threatening to paralyze them with the weight of despair.
