One poppet to rule them all, for all effects

A new device that is similar to the poppet shelf will be added, but it cannot perform all effects, and effects that require an item to be held or given have to also have said item added to the shelf. As a result, each rack on the shelf can only contain one poppet, one taglock, and one sympathetic item. Each poppet shelf has three racks though, so three poppets can be used. Not all poppet effects can be triggered in a shelf, however.

Throwing it into an active ritual circle has a chance of moving the ritual towards the victim, depending on the ritual in question.

Placing one on honey blocks causes hostile mobs of all kinds to follow you, even those with mentalities like spiders. It also causes mobs that are docile by default to aggro a player, such as bees. The victim is also heavily slowed down.

If given seeds, there is a chance the victim will not harvest as much from crops as they would’ve, even with enchantments.
