Elemental Mage

The most common variety of elemental mage is The Pyromancer, who specialises in fire. However, You can easily create mages of other elements by swapping out the Pyromancer's fire damage and fire resistance for damage and resistance of other elements. For instance, you could create:

• A Cryomancer by replacing fire with cold
• An Electromancer by replacing fire with lightning
• A Sonicaster by replacing fire with thunder
• A Venomancer by replacing fire with posion
• A Causticaster by replacing fire with acid
• A Shadowcaster by replacing fire with necrotic
• A Lightcaster by replacing fire with radiant

As always, ask your DM before doing so.
