My level 5 Fighter, by default, has an AC of 21 when buffed with a Ring of Protection, Warding Bond and Shield of Faith. When trying to hit my level 5 Fighter with my level 5 Barbarian, I have 35% chance to hit.
Buffing my level 5 Fighter further with Mirror Image, increases my AC by a total of 9. While this spell isn't identical to how it works in D&D 5e, in Baldur's Gate 3 it means that I now have an AC of 30 which results in my level 5 Barbarian only having 5% chance to hit my level 5 Fighter.
So, I faced off against those level 5 Githyanki Knights (on Tactician), whom managed to get a successful Hold Person on my level 5 Fighter, which sucks, but it happens. But they then proceeded to slaughter this fighter in literally one round.
This shouldn't be possible. How are they able to repeatedly hit a level 5 Fighter with an AC of 30 ? The description of Hold Person only states that they can't move, act or react, and of course that all hits within 3 meters automatically become critical hits, but there's nothing there that states that decreases my AC value.
Either I'm hoping somebody can explain me how this is possible, or it's a bug that needs to be addressed. I mean, sure it's RNG, but the chances of getting hit 4 times in a row when I should have 95% chance to avoid those hits seems highly unlikely to not be a bug.
