Could try. For now, Ultimate Doukutsu Trainer. (Used that for sequence-breaking during testing. Level 3 weapons forever helps.)

New races exist... IDs not available due to (what else?) unusable PC. But ID codes do exist for them.

Blood Valkyries: bloodthirsty mutation of Valkyries whose wings must be fully covered in blood to mutate. Some Taints negate this mutation (which, cannot recall). Most cases had Bloodlust Taint. Can further mutate into...

Twilight Valkyria (singular/plural unchanged). They are less bloodthirsty.

Both cases, Taints (usually) do not change.
