What Goes Up/Skill DC

(Dungeon Master): These two golden orbs are clearly more sophisticated than the one by the door.

LEFT-HAND ORB

(NPC): Elaborate Control Orb tells you, 'This sphere seems to control the barriers in the south corridor. The magic within its foggy depth seems complicated. After careful examination, you also notice a small override aperture on the side.'

(NPC): You tell Elaborate Control Orb, 'Attempt to use the orb (Skill: UMD)'

(NPC): Elaborate Control Orb tells you, 'It will take considerable skill to use the orb. You think you see HOW... at least in theory. (Use Magical Device skill test)'

(NPC): You tell Elaborate Control Orb, 'Open all the barriers (extremely difficult)'

<Successful result for 'extremely difficult'>: (Dungeon Master): (Control Orb Success) Success! All the barriers in one wing are down.
