Conduit:
A 5e Sorcerer Subclass

A Conduit’s body calls to the flowing strands of the arcane and potential power around them, instinctively drawing these energies into their being. Their innate magic flows through their body, manifesting in unpredictable ways.

As a Conduit, your body has the capacity to absorb, contain, store, manipulate, convert, and release arcane energy. As this energy channels through you, it may imbue you with enhanced speed, strength, or stamina. Perhaps you could even manipulate it to replenish your reserves, defend your allies, or amplify your magic. Be wary though of your body’s limits, as you can only absorb so much before it demands to be unleashed.
