Other items of his creation include Heward's Hireling Armor, part of his research into the archmage Heward.

However, the risk of accidental backfire is significant. Later in his life, he created a superior Greater Apparatus of Kwalish, an iron barrel which transforms into the shape of a small dragon capable of flight, and capable of firing a small cannonball from its mouth. Kwalish is best known as the creator of the Apparatus of Kwalish. Kwalish opened a gate to Jubilex's Slime Pits to clear the city to use for his new laboratory, which he then cut off access to allow him to research further. Kwalish then relocated to Daoine Gloine, inhabited by kenku worshiping a medusa than turned victims to glass. One gate resulted in a bone devil driving him out of the laboratory, and turning it into a monastery for its own cult. He spent years exploring it, and used much of the craft’s unique magical technology as a laboratory building planar gates of his own design. The rest of the party perished, but Kwalish found a wrecked planar craft of unknown origin. Kwalish, a scholar, joined an ill-fated expedition into the Barrier Peaks trying to find Daoine Gloine, a legendary city of glass creatures. He built the original "Apparatus of Kwalish" to explore the ocean and make contact with aquatic races. Kwalish was a wizard skilled in architecture and arcane engineering.

The Extra Life charity adventure Lost Laboratory of Kwalish used a stat-block for an evoker rather than give stats for Kwalish. Kwalish was "an elderly gnome arcane inventor" by about the late 500s CY. A skilled wizard, and an expert in both architecture and engineering, he is best known for inventing the Apparatus of Kwalish, a large crab-shaped aquatic vehicle which he made to explore the ocean and make contact with aquatic species. Kwalish is an inventor more interested in machines than absolutely anything else.
