So I was thinking about how hemalurgic spikes worked, and came up with this theory: if a hemalurgic spike was Awakened then it would be able to use the powers it had stolen. For example, since hemalurgy can steal from any magic system then you could spike a soul caster, embed a gemstone in the spike to hold stormlight, and have some sort of auto-soulcasting system that could trigger on contact. Since spikes don't have to maintain their original shape, you could make a floor plate that soulcasts anything that steps on it into smoke. Of course, I don't know if you can Awaken an already invested object, but this could have some interesting uses. Any thoughts?
