Nice spreadsheet. Gotta agree with Herzi, that column L is pretty great.

I'd suggest making the Achievements section less bulky by way of having a column for each of the standardized ones that multiple people have, then a single column for unique achievements and having it listed in a note which unique things they have. No need to have an entire column dedicated to Kasim's Lucky Ego (though it's quite apt for this to have a column to itself), Maeven's Mechanical Apprentice, Andrea's Mistress of Webs, and so on.
