Omega Labyrinth Life Strategy Guide:
Berune's Trial

Since you start with no items or equipment, keep an eye out for any equipment that drops and equip it immediately when it does.

As with other dungeons, you'll want to gain levels in the early floors where the enemies are easier, but you'll need to balance leveling with managing your hunger, as you'll be reliant on food to drop to avoid starving. Enemy difficulty begins to noticeably increase when you reach floor 4.

Floor 5 will always be the same. The floor will be a uniquely-shaped single room. There will be a number of enemies and items on the ground. Among other items, you'll find a Hot Dog Bun on this floor.

The boss of this dungeon is Grim Berune. She can inflict Blind and Paralyze. You can mitigate Blind by using a Mic. Casting Happy Lucky Clover will allow you to hit much harder and win the fight quickly.
