Eldritch Machine (Elite)
Trap
Level 2 Elite Blaster
XP 250

With a piercing shriek, one of the four strange devices that make up the machine releases a bolt of crackling energy that leaps to another device. As it absorbs the dark lightning, the second device shudders, sending waves of stone rippling out through the floor around it.

Trap: Each round, a bolt of energy extends between two portions of the machine, followed by a minor earthquake around one part of the machine.Perception     DC 10: The character notices that the energy crackling around each part of the machine is concentrated in a specifi c location in that section of the device.Initiative +5TriggerWhen the characters enter the room, roll initiative for the trap as well as the monsters. On the trap’s turn, randomly determine which part of the machine the bolt of energy originates from (roll a d4), and which of the two parts the bolt travels toward. (The bolt moves either in a north–south direction or an east–west direction, as indicated by the dashed lines on the map.) The trap first attacks each creature occupying a square on the path of dashed lines, and then attacks each creature in a burst 2 around the second part.First AttackStandard Action      Ranged 6

Until the end of the encounter, the damage dealt by that part of the device is halved.
     Thievery DC 10: A character adjacent to one of the squares where the bolts of energy originate can disable that part of the device by making a successful check as a standard action. A part that is disabled can no longer produce a bolt of energy.
