Arcane wellspring

An arcane wellspring was a sorcerer for whom the wielding of arcane magic came even more easily, almost instinctively than it did for even other sorcerers. When an arcane wellspring unleashed its power, it did not flow, but rather erupted, bellowing forth from them like an arcane geyser. To an arcane wellspring, magic was less a stream of power they let flow through them than a part of their very being, as much as their flesh or blood. Eventually, this became physical, to the point that arcane wellsprings actually transformed into pure arcane energy for a time.

Abilities
Arcane wellsprings had a number of unique features universal to them, acquired through their intense connection to the arcane. Unlike most sorcerers, arcane wellsprings had resistance to two or more forms of energy at once, rather than one, an affinity which transfered also to their attack spells for extra lethality against creatures with a similar resistance. Arcane wellsprings also had wider coverage for their spells, enabling them to attack multiple opponents at once, and with additional training they could teleport an equal number creatures hit by their spells.

Arcane wellspring spells were often transmutative in form, transforming the very nature of the sorcerer casting them. For instance, the spell sorcerous wings caused wings formed from arcane energy to sprout from the caster's back, allowing them to fly for a brief time. Sorcerous metamorphosis, however, was easily the most impressive arcane wellspring spell, transforming the caster from a physical body into one made of pure arcane energy.
