ROTR-B, SS-B monster
Check to defeat

The Ghost is immune to the Mental and Poison traits.

If your check to defeat does not have the Magic trait, the Ghost is undefeated.

This monster has powers that can leave a new player slightly confused in the digital version of the game. In addition to passing the skill check you must use something with the Magic trait. If you fail to use Magic then it doesn't matter how great your roll is the Ghost will be undefeated and return to the location deck. Part of what makes it so confusing that that there is not way to review what happened in the game recently.

TODO: Confirm whether check2 was only added in S&S, because I didn't have it listed for ROTR.
