Gründ

is the same as Quake Hammer Gründ. they are the same being. so i will add the same as the Quake Hammer Gründ page here.

First seen and fought by Rou in Day 142.

A boss monster found in the Labyrinth City Purgatory's dungeon: Mine of the Cyclops.

Wields an enormous spiked hammer that can cause the very earth to shake and buckle when it’s smashed.

The oldest and strongest of the three Cyclops bosses that can spawn in the boss room.

Also the rarest boss spawn.

Drops the [Unique] class magical item: [Demon's Smithing Hammer].

Eating his flesh while he was still alive, Rou learns 2 abilities: [Earth Shaking Hammer] and [Giant's Bloodline].
