How to start ritual:

Place ritual pedestal.
Place any two full blocks on the north, south, east, and west sides, each two blocks away from the pedestal.
On each block from step two, place any cave painting facing towards the pedestal.
Take an emerald and click it on the pedestal.
The ritual is in progress if you can see particles from the paintings going into the pedestal.
The ritual concludes with a lightning strike on the pedestal.
The ritual remains active for 7 days after its completion, and particles appear around the pedestal.
