Lore
In the hands of a skilled practitioner, thaumaturgy can be a force of terrifying destruction. At the heart of this school of magic lies the ability to call forth and command the latent aether within oneself through deep introspection.
To then mold that aether into sorcery, the thaumaturge makes use of a scepter or staff, within which is housed a medium—a natural stone imbued with magical properties. Thus armed, the thaumaturge is capable of wreaking considerable havoc via ruinous spells and curses.
Combat Role
Thaumaturge is a class that will allow players to use ruinous spells and curses to take down the enemy. They sling their spells from the back ranks of the party, well away from danger. Their spells have various properties, some designed to inflict heavy damage while others calmly put enemies to sleep to be dealt with later.
Any good Thaumaturge is only as good as his party protecting him. They are lightly armored and have very few hit points. Any Thaumaturge would be wise to have a Gladiator as a friend to protect them during combat.
