Apocalypse Spells
Apocalypse Spells are a unique kind of monster found only in Dungeons & Dragons 4th Edition so far. A variant of Living Spells, Apocalypse Spells are born when similar phenomena applies to epic level magic, such as that wielded by gods or the most powerful of archmages. These living spells are of incredible power, and rituals to summon and tame them are sought by the power-mad or the apocalyptically insane.
These monsters debuted in the 4e Monster Manual 3, which contained lore and stats for five Apocalypse Spells; the Prison of Mual-Tar, the Herald of Colorless Fire, the Shard of Uralinda, the Godslayer Inferno, and the Light of Amoth.
