— Nomad Animal Trader
Beast Trader is an Event that can trigger if the player builds an outpost within 11,000 meters of a Nomads owned location. When the conditions have been fulfilled, the campaign has a 5% chance to trigger each day if within 6,000 meters of a Nomads owned location, this scales down with distance until it hits 0% chance at 11,000 meters.
Once triggered, the Nomads will send a campaign to the player's base. The campaign will consist of a single squad, made up of 8-10 Nomads, 0-5 Goats, 0-1 Wild Bulls, 1-3 Pack Bulls, 1 Bonedog, and 1-4 Pack Beasts, led by a Nomad Animal Trader.
When the campaign arrives, the leader will request to speak with the player, offering to sell animals. If spoken to, the player can buy any animal in the campaign's party. Price for the animals can vary wildly based on age, skills, and species of the animal. But you can easily expect them to be several thousand cats for a single animal unless it's very young.
