First start with Iron [[Bowl|Bowls]] as they use iron, and are rather easy to imp. These can be used in altars.<br>
Once you get high percentage chance to create, imp Rings. These use .10 to create (you get .05 ring, .05 scrap). 100 of these fit in a BoK, so they are perfect for sacrificing and carrying around, and also only use very little lump to imp.<br>
