The Inquisition Oath allows Turning to affect fiends in addition to Undead. When used on hostile NPCs, a visual effect appears similar to the Fear status, indicating a successful Turn. However, when used on player characters (PCs), there is no visual cue at all, even if the effect succeeds. This means a PC could ignore the effect entirely without any way for others to verify whether they're genuinely unaffected or simply pretending, which can undermine the system.
I suggest adding a visual effect for successful Turning on PCs by Inquisition Paladins (and any other classes with similar abilities). This would enhance roleplay scenarios by allowing characters who invest in this mechanic to visibly identify potential vampires, rakshasa, or other fiendish entities and ensuring a fair experience for everyone involved.
