EO3/Yggdroid/Skills

This page details full data for the Yggdroid's skills in Etrian Odyssey III: The Drowned City. In addition to these skills, every class also has access to Common Skills. Contrary to other classes, it is not possible to use Yggdroid as a subclass, which means that their skills can only be used by Yggdroids.
