Albedo doesn't consider any of his skills to be secret as such so he has no issue answering the question directly. He tends to try to respond clearly to any direct questions while he can meander some with less clear questions that require philosophizing. "I am an alchemist and a scholar. I am also a knight of the order of Favonius."

So, any skills that fall into those categories are his to claim. He doesn't specify at the moment because not all of them are immediately useful, but: "I believe I should be excellent support for any experiments you wish to run."
