DC 30: The character notices the trap’s connection to the chest in the center of the room. (DC 10 after viewing the phantasm if a DC 12 Intelligence check is made first.)TriggerWhen a character attempts to open or move the chest in the center of the room, the jets make their first attacks as immediate reactions. They then enter the initiative order directly after the creature that triggered the trap, attacking each round. The blasts cease as soon as all creatures have left the room.AttackImmediate Reaction or Standard Action Close blast 4
