Surt utilizes both single-target and multi-target Fire and Phys attacks. We highly recommend bringing along demons that can block these types of attacks.

Surt absorbs Fire and voids Light, Dark, and Ailment skills, so never use these types of attacks as you'll only be wasting your turn. Likewise, it resists Phys but is not highly resistant to this type of attack, however, we do not recommend using Phys as Surt has Retaliate.

Surt also has two Support skills including Dekunda and Beast Eye which grants it two extra turns.

Dim, almost non-luminous, lightbulbs

Oval light casted in the middle of the corridor

General area appears to be dimmer

Less spaces in between wall columns

Appears distorted if you play with the camera angles

Look for a Deep Door Frame to Tell Real Doors and Painted Ones Apart

Real doors in this dungeon will have a deep door frame. Angle the camera to inspect if a door has a deep door frame to figure out if it's real or an illusion.
