The section of the ward removed by the conquistadors (Museo de Arqueología y Antropología, page 65, Peru) is less powerful, although entities like the kharisiri are still unable to touch it without being hurt (taking 1D3 damage per round) or spend more than a few seconds in its immediate proximity—even carrying it in a crate or bag would be impossible for them.

The spell used to create the ward is lost to time. The builders of the pyramid left no written records behind and there are no clues in the design of the artifact itself. It may1 be possible to recreate it through spontaneous use of the Cthulhu Mythos skill, in which case the Keeper should look to the Elder Sign spell for inspiration.
