In ages past, magic was plentiful. The world was young and the gods were filled with righteous energy. Powerful archmages and high priests surrounded their lands with artifacts bursting with supernatural energy. The mages and priests armed mighty knights with weapons and armor imbued with terrifying power. These armies fought terrible wars destroying entire cities down to ash and rubble.
The magics of old are now lost. They've become buried in ancient ruins and deep caverns. They lie in the sub-basements of crumbling castles or in cursed chambers of forbidden tombs. These monuments, however, still pulse with their terrible power.
Scattered throughout the lands, these monuments of power have attracted unnatural beasts, practitioners of dark arts, and the adventurers who hunt them. Few can tell what will happen when a living thing approaches one of these ancient monuments, and fewer still will live to tell the tale.
Ancient Monuments in Your D&D Game
As we discussed in Unhallowed Pillars, we can add interesting magical artifacts to our standard combat encounters and adventure locations. While we don't want to use them all the time, these ancient monuments can add spice to our game. Like relics, ancient monuments are intended to show a glimpse of the power that used to exist in the world, a magic now forgotten. When randomly selected, they add a bit of flavor to the game that even you, the DM, didn't see ahead of time. Or you can flavor them specifically to give your players a deeper knowledge of the world in which they adventure.
Monumental Effects
The effects of the monuments occur zone-wide. If you're reasonably close to the monument, you're affected by it. Effects are always on.
Monuments can be deactivated or destroyed with two successful skill checks taken as a standard action. Potential skills include athletics, arcana, or religion. The DC to deactivate a monument is between 10 and 20, often 15.

Another Layer for Interesting Combat
Though you don't want to add them into every battle your players face, these ancient monuments are a way to add some flavorful and mechanically interesting variables into your more tactical encounters. Give them a try.
