What all can a larkin eat. For example could it eat a spren, a perpendicularity, the well of ascension, god metals, shades, a hemalurgic spike/metalmind, and/or separate Kelsier’s cog. shadow frome his body. Another question I would ask is if you could make new honor blades in the horneater peeks.
edit: sorry I meant shard blades since they are a alloy of cultivation and honor
