A thought for an item that might be cool.
A pot of dirt. It has a unlimited use power, that when activated puts a place able on the ground, in which you can plant a single seed, and grow an efu plant (not a zurkwood or blue fungus).
You can then carry your plant about with you, placing it down whenever you want to harvest from it.
Make it fairly heavy, and perhaps put a note in the description limiting it from being stored in chests, boxes, or bags, and limiting each player from carrying more than one at a time, to prevent walking hydroponics operations, and grow ops.
Just a neat way to always have access to that one plant you always need, without having to leave it out to be pillaged constantly.
Might be cool, if that didn't make me think that people would start making herb mules to help each others alchemists.
The current scarcity of plants makes things competitive which I can't think is a bad thing.
