+1. I like the idea.
I would like it to spawn/teleport the imp near you, as you wrote, but also i think it could be cool if it catches imp for you, not with 100% success rate, but still a high one 😆
then it ofc. should be more expensive, like 5-10 tokens (matching with the successrate) 😆 so it becomes "the ultimate" item for imp cathing, and a grind item.
