Sorcerous Origin: Cataclysm Mage

As a cataclysm mage your innate power is born of the mysteries that ended four ages of the world. This power may have blossomed in you following intense meditation, or its manifestation may be written into the Prophecy itself. Your destiny drives an obsession with the past, and you are haunted by visions of the great cataclysms yet to come.

The four great cataclysms are each revealed to you in a dream or vision upon fulfilment of a personal prophecy. Each is a key to decipher the secrets of the draconic Prophecy as a whole. Your DM may determine your personal prophecies for you, or you may wish to come up with suitable ideas together. A good prophecy should be attainable, but esoteric. Consider a short poetic verse or an ironic development tailored to your sorcerer's past and present.

Cataclysm of Flesh

At 1st level, you draw power from the destruction of the Dhakaani Empire at the hands of the aberrant horrors of Xoriat, the Realm of Madness. Your spells tear tiny holes in the fabric of reality, through which the magics of that far realm work to corrupt Eberron.

Immediately after you cast a spell of 1st-level or higher, you can use a bonus action to temporarily corrupt the flesh of up to one target of that spell. That target gains disadvantage on their next attack roll or saving throw.

Secrets of the Fallen

Your awakening to the cataclysms that have shaped the world grants you an innate understanding of the descendents of long lost civilisations. Through these aspects of the Prophecy, you gain instant knowledge of histories it may take scholars years to uncover.

Starting at 1st level, you gain proficiency in the History skill, you can speak, read and write Goblin, and you gain advantage on Wisdom (Insight) checks against goblinoids.

At 6th level, you learn to speak, read and write Giant, and you gain advantage on Wisdom (Insight) checks against giants.

At 14th level, you learn to speak, read and write Abyssal and Infernal, and you gain advantage on Wisdom (Insight) checks against fiends.
