Encounter-a-Day

The ceiling of a large chamber is covered in a grid of shiny, chrome spheres, each suspended from an iron rod. A series of alcoves line the wall. Each of the alcoves has a hole in its ceiling. The chamber smells distinctly of ozone.

As soon as one of the characters gets about half way into the room, the doors slam shut. A buzzing sound can be heard, and the hairs on the backs of the characters’ necks begins to stand on end.

A moment later, a golem drops into one of the alcoves and begins attacking the PCs. As soon as it begins, the chrome spheres on the ceiling start shooting bolts of electricity at anything under them. Every round, anyone underneath a sphere gets zapped, harming the PCs and healing the golem.

The spheres themselves are extremely fragile, and any damage at all will shatter them. They’re also very small, though, and so are somewhat difficult targets.

If a character climbs up one of the holes in the alcoves, he’ll find above the ceiling a massive power generator. If destroyed or disabled, the spheres will lose their charges.

If you want to increase the lethality, you can thrown in some more electrically-based monsters. For example, Shock Skeletons, which are skeletons plated with various metals; essentially, walking batteries. They can drop from the alcoves in random intervals, and unleash electrical blasts at the PCs or at the golem.
