At the start of each day, a creature affected by this Curse : (1) Abyssal; (2) Enochian; (3) Draconic; (4) Abolian; (5) Infernal; (6) Primordial; (7) Sylvan; (8) Nagh. the Target can only speak in this language until the next sun rise, and understands anyone who speaks in this language.
You observe the victim's speech change with each dawn, their words shifting to unfamiliar tongues. Today, they speak in the guttural growls of Draconic, comprehending only those who reply in kind. Tomorrow, it may be the melodic whispers of Sylvan, isolating them in a new linguistic prison until sunrise.
