D&D 5e Darkness Spells: Eclipsian Bolt & Devour Light
These two are just a few of the many spells planned for my next compendium, the Tome of Twilight.
Enjoy these spells that play with the light, and find even more of them on Patreon, alongside all the new exclusive content for this Compendium.
Regarding Devour Light, yes the darkness stays until dispelled or daylight-ed, which falls in line for a 5th level spell, when you consider the erupting earth a 3rd level spell, can create permanent difficult terrain (granted easier to fix, but it's 2 levels lower)
Enjoy & Take Care!
