My friends and I were playing Elder Signs tonight and ran into an interesting question when attempting to complete this adventure card.
One player had just completed the first task and was attempting the second task, but failed. In his failed dice pool was a terror result, so the card's effect came into play and a Doom token was added to the Doom track.
As a result, a monster appeared. Every adventure card in play had a monster on it already, so the only logical place to put the monster was on the Do Not Touch The Exhibits card.
Does the monster get played on that card and immediately add it to the current tasks in the middle of this turn? So the player now faces the failed second task again AND the monster to complete the card, or does the monster get played on another card that already has a monster?
