To prevent spam, a password is required to add new Mutations - contact Kevan or Ben to get it, probably.
If your power is a Flaw, writing "Flaw." at the start of it will automatically add an italicised explanation when it appears in the archive.
A Request: To avoid the archive filling up with ambiguous or confusing Mutations, please only submit stuff that you've actually played with, or are fully confident about the sense of. We might implement an approval-pending system eventually, but until then, test your Mutations in battle. Thanks.
