Spirit mirror really doesn't feel so broken that it needs to be bashed into a huge sign saying 'look at my equipment'. It already felt kind of abusive that people could see it was there from the buff list.

The whole point of stuff like mysterious is entirely so things like this can be a surprise. You are sacrificing a good bit for a gamble that half the time - Or more - Doesn't pay off. When my ranger runs into spirit mirror, it never even impacts how things play out.

If it's going to hammered in final destination fox only style, it should also recharge every few turns or something, or get a skill to let you re-apply it.

Mysterious has a myriad of other things it can hide, like your exact HP/FP values to avoid people making risky plays for a guaranteed lethal if they were aware of your remaining health.

In the event you have no idea who your opponent is or what they're running Spirit Mirror can indeed be a gamble, but if you've got your opponents setup downloaded and know they heavily depend on projectile-based attacks for damage you just slot in a Spirit Mirror. Very few out-of-combat applied statuses are this impactful when hidden by Mysterious. Something like a custom-tome reflect is going to be seen cast and only linger for a round or two, whereas Reflect Projectile lingers for 10 rounds and is active before the fight begins--longer than most 1v1s will go for, where Spirit Mirror sees the most value.

Making Spirit Mirror plainly visible would hardly impact its effectiveness, it wouldn't need to be buffed to compensate for no longer being able to trick people, as most players will already assume someone with Mysterious has a Spirit Mirror, and only ever be tricked by it due to undocumented changes to what used to be projectiles changing into non-projectiles or being in the minority that just doesn't know Spirit Mirror exists. Knowing its there still means you have to play around it unless you can get by dealing 0 projectile-flagged damage the whole fight or remove the buff without losing any momentum/taking damage in the process.

Spirit Mirror has always been something you'd use to counter a specific playstyle, I will shed no tears if it's made so that only those who actually wear the item get to benefit from its existence rather than being a boogeyman to anyone who might be affected by it when they see Mysterious/Mask of Metal.
