(I just kind of skimmed over Meli's stuff before, but I'm planning to do an actual post explaining more later.  Basically it's going to be like originally stated, hat can provide advice on magical/alchemical stuff and work as a pocket dimension for storage of stuff.<br/><br/>The dagger, is going to work off blood magic and allow her to steal others traits for a limited time depending how much blood the blade tastes. So, say she's tired of being tiny, she could poke someone with the blade, get their blood on it and use that to steal their height for herself. But... Doing so uses the blood like fuel, so once it's used up effect is over. The more blood it takes in, the longer the effect lasts. Even though it's very useful she's likely to exercise caution with it because she knows blood magic is very dangerous and tempting magic and like Evelyn, the blade hungers. She needs to remain stronger than it so it's desires don't turn her into a serial killer who uses the excuse, 'but the knife told me to!'  The blade can do multiple traits at a time, but only one per person, so can take the height from person a, the strength from person b, and so on. )
