Helldras are first encountered on 12F in Etrian Odyssey II: Heroes of Lagaard. They can also be summoned by Snowsouls, which are found throughout the 3rd Stratum, starting from 11F. As FOEs, Helldra are passive and do not move during the day. Once it is night, they begin patrolling like any other FOE. Helldra have no elemental weakness and are somewhat resilient to magic attacks.
