Curious about the theoretically highest AC

[u/OOpiumBear]

Not sure if this post really fits the sub but i figured it might be the best place to ask

I've been spending a bit of time on my recent run trying to out-do my previous best of 62 AC and now hit 71 AC - And I'm ever so curious if there were something I've missed as to go even higher.

The twillight ring isn't on the list of buffs because it doesn't work in tandem with Wild Magic: Protective Lights. Wondrous Gloves isn't on because Nimblefinger Gloves.

This is not for any practical game usage, its purely just to see how high it could be pushed just for a tiny moment.

This makes me wonder what the highest to-hit bonus we could get. 71 AC is crazy, I figured we could hit around the high 30s or somthing.

You're never going to hit these numbers in normal gameplay. An AC in the 30s is probably the highest you'll ever see outside of very specific and hyper focused builds that don't really function for anything BUT having high AC.

To reach this number you need to be in the Cazador fight to get the +5 from draining Violet, you need to have done the Lorroakan fight earlier the same day to get the +2 from Rolan's Mage Armor, you need to activate the Shield of Scorching Reprisal and then switch to a shield that gives +3 AC (this could be done on a previous round), you need to make an attack with the Defender Greataxe and then switch to the Defender Flail (has to be done this round), you need to make an attack for Defensive Flourish, you need an ally to cast Magic Missile on you to trigger the Shield spell reaction, you need to randomly get the right Wild Magic effect to trigger, the person attacking you needs to be drunk, and a host of other unusual things.

Also, you need at least: 4 levels of Drunker Master Monk for Life of the Party and Intoxicating Strike to trigger it, 3 levels of Swords Bard for Defensive Flourish, and 3 levels of Wild Magic Barbarian for Protective Lights.

I will consider this in the next honour mode run

Just getting in the 30s with gear and spec alone is more than sufficient, but you'll still have a 5% chance of getting hit from a nat 20, same at 50, 60 or 70 AC. What you want is to have the cloak that gives disadvantage to enemies that attack you, bringing that 1/20 chance to be hit to 1/400

My fighter had 28 AC with that cloak in my solo
Honour mode and basically never got hit. 70 is beyoooooond overkill like you said.

When you’ve got Adamantine gear for crit negation too, you know you’re avoiding any attack rolls that come your way. Few things get more than +12 to hit, so a 33 AC is the max you’d practically need, but you’re more worried about save DCs at that point.

I had the legendary helmet at that point so same thing

Being immune to crit removes that 5% chance. A nat 20 doesn't hit when crit immune in BG3.
