Ah yes, touch AC, that one part of a character's defensive stats that everyone forgets about until it's too late.

Story time! Tell us a tale about either you or a monster that was taken down by their touch AC.

Hey, did you know that an uplifted wight can walk among normal folks? Did you know they make insanely devastating monks? Seriously, get the right splat books, and you can be making four to five unarmed attacks at level eight. Bear in mind that this just makes a monk that's on par with a mediocre fighter. But once you make that monk a wight, and you start making touch attacks, this build becomes incredibly broken... At low to mid levels.

When you reach places like the far realm, or the nine hells, touching your enemies can be extremely dangerous. There are many things covered in acid, or magma, or very potent drugs, or that one sludge demon made up of infernal pollution.

Heh. Playing pattycake with the beholder's eyes would normally be a great way to die horribly, but a wight monk can kill one in a few rounds.

Wait, there are beings made of potent drugs that enter your system based on touch alone?

Would that be a Stoner Golem? I can see that being very popular at most human parties and get togethers.

Check the monster manual, or the fiend folio, I forget which. There are stoner imps that secrete psychactive drugs from their claws. Larger demons force them into servitude, using them to get high.

Touch AC is why I love playing an alchemist in my friends' Carrion Crown campaign. Giant armored behemoth coming this way? Chug a Fox's Cunning, INT-boosting Cognatogen, and Targeted Bomb Admixture, and unless the baddie has some insane DR or immunity to the damage type you're using, you'll be ripping through him.

Of course, I have absolutely no head for min-maxing myself, so I didn't actually KNOW this when I picked the class. I just thought playing an alchemist sounded cool.

That reminds me of the alchemist in a PF game I was in. We needed a tank so I made a Tiefling skirnir with 22 ac at level one. The most damage I took in sessions was from the alchemist fumbling with his fire potions and hitting me in the back of the head with one. So glad I had tiefling fire resistance.

Two words. Pathfinder Gunslinger.

DM's Goliath Spider(CR11) went down in two rounds despite having a regular AC of 25 and us being only lvl7. Sure, I went down in the second round too but that's just details. I lived and he is now a Exoskeleton minion of the Oracle...

he uses him as home and carriage. I'm sure he's going to make a ladder from his mouth or something more elegant.

What is it with Pathfinder, Gun-users, and making carriages out of the exoskeletons of giant spiders? Because I've done almost that exact same thing, except with a Spell-slinger gnome.

I have a party member in a PF gestalt game running Alchemist//Kineticist, which means that he basically never has to roll against standard AC-- only his emergency natural attack and eventually some of his boosted Kineticist attacks will have to deal with normal AC.

Amusingly it took him three or four sessions to figure that out. Once he did, he stopped ever missing anything.

To hit the thread from the reverse, in the same game my GM's pretty much resorted to distracting my character with mooks while he tries to actually hurt everyone else, because her AC is... amusingly good. AC 26 at level 4. He considered Touch attacks for a while, which of course make life easier... but her Touch AC is still a 17. Which is as high as our party Fighter//Warlock's actual AC. Flat-footed is worse; that one's a 19 for her (meaning, on par with the rest of the party's normal AC).

If she wasn't continuously nailed by random crits, she'd be nigh-invincible at this level. I'm fairly certain she's eaten a crit in every session that had more than one fight.

Oh, and eventually this same character will be able to target opponent's Touch AC with her normal attacks pretty much on a whim. Right now she just has to give up a bit of her damage to do it (the Magus is a really, really fun class).

Sorry to say this, but I'm going to go a little off topic with this one. Recently one of my friends is going to run a lv 9 Pathfinder one-shot. I decided to play as a monk since I love them and then I decided to just concentrate on AC. In a round I can get up to 44 AC IIRC.

Then I felt something. I said "Hey, how high can AC actually go as a PC by himself in one round?" and I actually got the answer I believe. It's....100 AC. That's not a typo, one hundred AC.

I got a feeling that's the build Luffy here has (which is a kobold 15 monk/5 duelist).

This has long since ceased being a boss fight. This is straight-up PVP.

When was it not?

How is that a bad thing? You know you've done something right when the GM goes out of his way to kill you.

Incidents involving AC are kinda...limited to DnD. But as for stories involving things that the players have no defense against...that I got.

In the Bleach of the Gods game all of our characters are warriors. Except there are three types of character for Weapons of the Gods. One of these, the Courtiers, can inflict conditions on others through the power of their words. Since the whole game was built around warriors fighting we hadn't exactly worried about that. So of course the GM hit us with a curve-ball one arc and a noble starts using Cortier powers on the team, forcing two of the party to start fighting each other. Without a cortier of our own, we have no way to break the spells or even counter them.

Fortunately I got creative, using my rocket powered spike ball and chain (weapons got weird), I used the engine noise to drown out their words so they couldn't inflict MORE conditions on the group. (It was argued that Sagara wouldn't understand courtly magic, I pointed out that when the noble said something, people did it.). This led to the noble resorting to graffiti art to use their powers, and me slinging mud around to try and keep their message illegible.

T'was a fun fight ^^

You know what's actually good for not having to worry about your touch AC? Monk with Vow of Poverty. Yeah, that's right, I said the dirty sentence and I'm not washing my mouth out.

You know what else monk AC applies to? Flat-footed + touch. Still losing dex though.

you seem to know a bit about monks.
i should play monk sometime.

hah, ONE Story?
I paly a Warlock most of the Time (updated to Pathfinder granted, so not toally underpowered but still more or elss a mediocre range fighter with some nifty "Always possible" stuff.
And know what? his at will Eldritch Blast is a Touch attack. ;)

Our barbarian rages at how often I hit things he doesnt, and with not THAT much less Damage thanks to the right evocations.
