The Interdiction Ritual is a ritual added by Blood Magic. When activated, the ritual will repel mobs in a six block radius centered around the Master Ritual Stone. The Interdiction Ritual is the opposite of the Ritual of Containment.
The Interdiction Ritual costs 1,000 LP to activate, and while active will consume 10 LP per second to repel mobs in a six block radius. Both passive and hostile mobs will be repelled by the ritual.
