Give Reapers and Apertaurus a racial ability equivalent of the Spiritual Sensitivity trait. That's their entire gimmick. It defeats their entire point for them to be insensitive to spirits, and if people want to make snowflakes from Lazarus who aren't sensitive to spirits, that's fine - but establish the norm of them being sensitive to spirits mechanically. They are the world's best exorcists naturally.

Also maybe make Spiritual Sensitivity applicable to characters outside of battle. I can stand next to someone but never know if they're harbouring spirits until we maybe draw our weapons and stare at one another with the intent to fight. There are a myriad of ways you can go about this but I can't imagine it'd be too hard to code using a verb on someone within a specific range and getting a message telling you if they have spirits - and maybe telling the person you used the verb on that you stared at them weird for a sec.
