You go to the Basement and interact with a ring of salt there. After 120 seconds all gens get 15% repairs and you become Broken until the end of the trial. Other survs see your aura, so they can go and also interact with the circle and speed this up and if they also have this perk it goes even faster. Only the surv who started the Invocation gets broken. I don't think anyone will use it in it's current state, but it's cool that it's indeed a brand new type of perk.
@@ZamasuManzon it being regressable makes it pretty much worthless imo. It should be like Brand New Part instead, and REDUCE the max progression level of the gen by 15% instead.
