The limits of reality have been stretched by many spellcasters and arcane studies over time, but the Arcane Mechanic takes the mysteries of magic and combines it with mondaine creations to support allies and devastate enemies.

Combining knowledge of the arcane with mechanical prowess, an Arcane Mechanic controls the battlefield with powerful constructs powered by magic.

Level 14: Sentient Creation

The Defender has also developed a personality and can communicate with you telepathically.
