Mechanist

Profession that can be unlocked through Achievements. Provides a global 25% boost to Robot stats, and the ability to craft your own robots.

One of the most customizable runs possible, due to the number of special traits that you can attach to your robots. Can be difficult to start early on due to the steep Crystal and Mythril costs, but can peak far higher than many other strategies. Also the most receptive to Ranged Weapon gimmicks, due to the ease of adding ranged traits.

Aside from the ability to upgrade them, Robots boast high stat growths, the Crystal element type (halving damage from all sources save Radiant and Shadow), immunity to Bleeding and Poison, and the Loyal trait.

In addition to materials, Robot upgrades will use Stat Increase slots, and so items and genetic traits which increase such will be valuable.
