[[Image:Object-lightning-spire.jpg|frame]]Lightning Spires are [[Objects]].
These turret-like defenses are found only in the [[Arcane Sanctuary]] in Act Two. They shoot out lightning bolts from a distance and novas up closer, and are tough enough that most players simply pass them by, rather than pausing to kill them. They are worth much more experience than most monsters (on Nightmare and Hell; they're nearly worthless on Normal) but they can not be leeched from and never drop any items.
