A Fighter type Monster Room introduced in Boss Monster: The Next Level. It is one of a few cards that features a new uncover ability, and can thus be called an Uncover card.
The effect of this card allows it to be covered and then uncovered continuously to activate its effect. It is recommended to have another Monster Room in a dungeon at all times to make use of this card's effect. It can pair nicely with Monster Rooms that have a "If a Hero dies in this Room" effect, like Golem Factory, Vampire Bordello, Succubus Spa or Fangroot Garden.
The monsters featured in the artwork have also appeared in other cards, namely as the artwork in the original Boss Monster spell, Giant Size, and in the artwork of the Item Card, Star of Invulnerability.
