Imagines are summon niggas. They were a thing in OG BP too. They have rarity grades of purple and gold, gold being better. They mostly come from field bosses (gold) or elite mobs (people) which can be farmed, though you cap rewards at 50 kills per day, a crazy number to try and reach. Every day you get 2 field boss keys and 3 elite mob keys to get substantially better rewards. The drop rates for the thingy that let's you craft the summon is pretty low, but the drop can be bought out sold on the auction house. The real issue is you need copies of the thing to upgrade its effect. Not a horrible prospect for the purple rarity, but gold gets expensive since you're very unlikely to get copies naturally. There's also a gacha for special NPC gachas. These are even worse to try and get, and cost more of the other materials to upgrade. And chances are, each season we get new NPC imagines
