提案/Suggestion
As a way of future proofing the eventual inclusion of subspecies and rare species as new riftborne monsters, move the riftborne icon to the lower LEFT corner (or alternatively upper right), such that it will not hide the symbols used to denote subspecies and rare species.
現状/Current Status
If a subspecies had a riftborne form added today, the icon denoting “this is a subspecies” and the icon denoting “this is a riftborne monster” would overlap. Only one would be visible.
