Yeah, best case scenario, It’s mathematically the same as a +1 AC bump in that one more value of the d20 attack roll would be a miss than would be without it. Except the extra roll value is between 6 and 15 points above what would currently hit your AC, which is worse. If they already have to roll middling to very high in order to hit you, that 6-15 points could be higher than it’s possible to roll without criting (i.e. >19)
Even assuming your AC is abysmal, like 10, if you roll a 10 on the die, you now get misses on a roll plus modifiers of 1-9 and 25 (excluding crits). If the attacker has total modifiers of 5 or less to hit, that 25 isn’t doing anything at all as they either couldn’t hit it or would crit to hit it. So in order to keep your extra point relevant, you would want to save a low roll, ideally a 1, for an extra point 6 points above your AC. But even that gets less useful the higher your AC is. Too high on either your AC or your roll and you have the same problem, the ring does nothing.
This ring is maximally effective the lower your AC is. And even then, best case scenario, it has the total effectiveness of a +1 to AC.A ring of protection already provides you that mathematical advantage. Plus ring of protection is less rare.
Yeah, this seems only relevant if the DM is really stingy with magical items so players don’t have anything better to attune to. Usually I think this is a horrible idea, but I could see a campaign where you only get really weird not super powerful magical items and having to make them work. It probably wouldn’t be fun, but I bet there’s a few items out there it’d work for, though this isn’t one. This one is just boring and not useful.
Seems like a waste of an attunement slot.
Might be worth the attunement if paired with some other effect. Maybe +1 AC or some other effect.
Even such a low % chance of hit helping, compound on top of that of the % chance you even remembering it should be a miss on that specific roll.
