Five new sorcerous origin options are included in this offering from The Copper Sanctum: Blood of the Battlefield, Blood of the Sphinx, Elemental Lineage, Fiendish Birthright, and Medusan Legacy. This supplement sifts through some sources with deadly origins.
Blood of the Battlefield
The Blood of the Battlefield flows through the veins of these sorcerers. Infused with the magical remnants of war, these sorcerers are powerful, magical warriors.
Blood of the Sphinx
The Blood of the Sphinx may make a sorcerer more likely to speak in riddles, but it also grants them several temporal powers, minor teleportation, and protection from telepathy. I'd say it's worth it overall.
Elemental Lineage
Sorcerers with an Elemental Lineage are intrinsically tied to one of the four planar elements: Air, Earth, Fire, or Water. Their connection culminates at 18th level when they gain the ability to transform into elementals.
Fiendish Birthright
When a sorcerer claims their Fiendish Birthright, they unlock an ambitious and complex journey. (This is the most elaborate subclass I've made to date)
Medusan Legacy
For a very long time now, Medusa has been misrepresented in D&D. I can't fix everything, but my Medusan Legacy for sorcerers does include more details from the myths of old.
