I asked a similar question for my signed copy "Is it possible to use Hemalurgic spikes to steal multiple attributes from the same person?" so I would recommend another question
My second question for Brandon (I bought both books) was "Is it possible to create a Hemalurgic spike with several stolen attributes?" so that's also a similiar question to yours.
Lastly, I'm new here (created the account for this post) so I'm wondering, is there any place to post what questions I've asked to avoid duplicates?
