I see why you'd want this, and i do think it's a good idea, but I just think it's too much utility for a class that already has a LOT of personal utility.
I mean biolo already doesn't need guyak, gets 10 levels of enlarge anyway, 20 levels of gympass, and the cart which has what? 11k weight limit, I think this isn't necessary.
What surprises me is you taking all your recipes everywhere, all the time. Maybe knights should be able to have a specific storage option that has it's own weight for their recipes too, or assassins for their GX poisons (playing devils advocate here).
Storage has a 30k item stack limit iirc, so I don't see why crafting in a dungeon is so necessary that you can't have a dedicated storage for materials as there are 3 storages, a guild storage if you make one specific for your biolo, a Master Account storage and then 7 premium storages (5000 cash points ea).
