Possible reference to the Dragoons of the Final Fantasy series through the helm/visor design and the Jump ability of that class.
This card was originally a Fighter Item, but became a Universal Item over the course of development.
When a Hero “ignores” a Room, it skips that Room and does not trigger any damage or abilities of that Room. It treats that Room as if it does not exist, so it does not “survive” an ignored Room.
Given the text of the card says "in any dungeon", this would indicate that it cannot be used on a Hero who is at the entrance of a dungeon, preventing you from using it to jump over the first Room.
