Hey everyone, just wanted get a feel from the community for a one shot encounter I promised my group I would run for them.
Scenario:
-I am running as DM and my group wants to fight a one off battle as level 20 characters with lvl appropriate gold division, there are 5 of them.
-the field will be an open arena 400 feet long 275 wide and 125 tall.
-anything available in hero lab is approved for making characters that is not 3rd party
- all party members and monsters will start out prebuffed.
-very experienced group average years of gameplaying under their belt is 7 years, ranging from 1-15 years.
- double blind set up. They don't know what they fill face and neither do I with the exception, they are good/neutral party and enemies will be neutral/evil aligned.
: questions: what is an appropriate CR level for the above criteria?
- what changes can/could be made for a balanced and enjoyable battle?
- what difficulties would you expect to run into that could break the battle or make it one sided?
:Personal opinion/self answers;
- I think a CR 26 would be appropriate
- seeking opinions
- 3 dimensions will be in full use. Certain protection spells or banishments for demons/devil's.
I appreciate any help or I sight y'all can provide. While I am an experienced gm, I have never run a one off battle before at such a high level. Also keep in mind these players will be min maxing to the extreme.

CR is a guess at best by that level. They might be able to handle multiple CR 26 monsters, or one with a few mooks might smear them. There's a wide range in people's abilities at min-maxing and no average case to default to.
There are dozens of ways of easily ending the battle that the PCs might have and I have no idea which you have overlooked. The size of the arena and a plan to use it all suggests that they won't be able to get away with the 'fly above the enemy and shoot' plan, but like I said, dozens.
Not enough data given to help you sorry.

Party of 5 level 20's? You want it to be a CR 26 encounter?
Take Choral the Conqueror from the end of the Kingmaker AP... a CR 25 Advanced Great Wyrm Red Dragon... and surround him with 32 Iron Golem Archers.
Who? I seem to remember a fae was involved... sort of a half-goddess with horrible spacial-sense. Nothing as straight forward as a dragon.

We're talking about making an encounter for 5 level 20 characters that honestly shouldn't know what they can do and certainly aren't ready to cooperate.
Then again, you're running a group of monsters that you probably aren't comfortable with either.
CR 24 would probably be appropriate unless you let the party have more than WBL. If you have, add 2 to the CR. WBL is a real shackle. Oh, part of that shackle is enforcing that the players can't exceed the percentages suggested in how the wealth is distributed.
Enjoyable battle: make a well rounded encounter, go in with no expectation of winning. Don't even expect to put up a real fight. Try not to let a single PC kill everything. Make numbers about equal to the party.
Difficulties: You've just let loose an entire group of experienced players to make a level 20 munchkin. Don't expect team work, don't expect anything remotely balanced. Expect 5 different one-trick ponies that should kill anything you bring to the table in 1 round or to fail miserably due to a bad match-up.
If it doesn't feel like you've been bent over the table and taken advantage of, they aren't as 'experienced' as I would expect.
If you want to win, use Robots and equipment from the Technologist sections of the rules combined with Anti-Magic fields. But seriously, don't even try to win. That would just be bad form.
If you accidentally win, that is fine. Just don't try to win. Try to make it fun. You might want to introduce each and every NPC and PC before the battle begins. That will help stretch things out and give the players a sense of tension and hype things up a bit.

Choral the Conqueror is in the back of the AP. After you deal with the bat-$#!+ crazy Fey, you can continue playing and this big dumb dragon shows up claiming to be Choral the Conqueror returning to unite his old kingdom, or some such nonsense. You either take a knee and kiss the ring, or you stand your ground and hang his head above your throne.

There are a lot of super powerful monsters you could throw at the party, and you could make team. You can make a party of level 20 NPCs to set on them.
Another thought is you can create a nonconventional gladitorial competition where the party's goal is not to destroy the other side but rather to protect or deliver something.
The match begins with 2 NPCs on either end, and an army of NPCs on the sides of the arena. The 2 NPCs are the PC's allies.
The event begins with a teaser with one of the 2 NPCs, a damsel, presses a love note in the party's hand.
The party's goal is to unite the 2 lovers and bring them together to the castle. They have to deliver the love note to the other side of the arena with the rest of the NPCs trying to stop them. (Will the party take the princess with them? Will they split the party to guard the princess and deliver the message? Will they forget about that altogether and let the NPCs kidnap the princess?) When they deliver the loveletter to the prince, he will charge across the field to be with the princess, and now the party has to protect him. Once they are united, they have to fight their way to the castle (a circle marked off in the arena, maybe built up to look castle-like, maybe the NPCs will occupy it and the party will have to beseige it.)
They lose if the love letter is destroyed, either of the lovers is rendered unconscious or dead.

Thank you very much for your guys help. It has definitely given me ideas to chew on.
Avr- no worries, you confirmed one of the difficulties I was worried about, but hopefully the ceiling will still give them room to maneuver without letting them sit back and take pot shots.
Merrill- I think I will blend a few golems into the battle but just enough to be annoying for them. I am hoping that their excitement on using lvl 20 power houses will distract them enough that they won't be working together as well. Before this the highest level they have achieved is 17.
Scott- I do have a bit of plot planned, a classic champion of the gods type deal. Not too deep but enough to add flavor.
If you have other comments or ideas please don't hesitate to share.
I was thinking of throwing an arcanist in there specialized in dispel/counterspell but I figured that would be too difficult for them.

Casters who are good are more than capable of soloing CR 30 bosses like Cthulu and various Demon Lords. I highly suggest going for quantity over quality here.
This is terrifying. How is the game even fun at that point?
Wizard: "Hmm, Cthulu... I cast WIN THE GAME AGAIN, again."
Boring.
I built a Panache using martial that went from level 9 to 12 without taking any damage, and I retired him because he was boring.
I absolutely cannot imagine why you would dedicate so much of your time to something handed to you served on a silver platter so ridiculously easily... like don't you have anything better to do? Barely lifts a finger, breaks reality somehow more than the God of insanity.
For everyone else, it's a struggle and takes work, it is a rewarding experience to overcome such great odds and survive to see the sun rise after beating Cthulu.

I think this is a bad idea. At most, such a character would shut one caster down. It doesn't defeat them, it just ruins the fun of one player. It would literally be better to run into someone with a ring of spell turning because at least you get to see your spell do something.

Countering has always been part of tabletops, I don't see why it should be considered a F-word. Especially at these high levels when not having denials is the strange thing.
At one point, players should adapt, it's not only on the GM and it's not like the player can't do something else.

I agree with both of you. My concern with not having something to counter their spells and buffs will make the battle very one sided. As a lvl 20 caster can pretty much just go invis and fly around firing spells Willy Billy with none able to catch up to them.
I already know they are gonna be using communal airwalk which will make the entire team airborne. (They always use the spell) in addition to every protection possible in the book.
Traditionally in my group, most of them take some kind of magic class or a hybrid class that has access to magic divine/arcana in one way shape or form.
I was thinking a good in between may be to have him only counter/dispell the buffs and make the arcanist more of a debuffer and crowd controller.
This way my monsters will have a chance to actually hit them without just making a grapple machine.

I was thinking more like 2-6 monsters that are CR 20-24 that add up to a CR 26 encounter.
Like, a CR 26 monster is 2457600 exp, but if you break up the encounter into 3 monsters, x1 CR22, x1 CR23, and x1 CR24 monster, it ends up being 2662400 exp, which overall is a CR26 encounter. Or you could go x1 CR24, x1 CR23, x1 CR20, and x3 CR18, that is 2816000 exp, but still considered a CR 26 encounter. If you only want 2 monsters, then x2 CR24 monsters is exactly 2457600 exp, which is a CR26 encounter as well.
Anywho, you can make up w/e encounter you want here: PF CR Calculator
And if you have Combat Manager, you can take basic monsters and buff them up to whatever CR you need for the encounter. Easy peezy.

You really need to limit what they can use, as there is a large number of "I Win" scenarios PC's can use in a build:
I ran many years of PvP games at GenCon, and every year the majority of the players came with the same build I banned the key feature.
- Gate - 8 of 12 players brought a Solar to their level 12 PvP
- Leadership feat doubles your effective power.
- Anti-Magic fields - everyone will be a barbarian UMDing a scroll of antimagic field.
- Crafting double or triple buying capacity.
- Xanthuun Tablets - infinity concentration.
- Quickening Diamond material components - 8,000 gp all casters will always quicken their spells.
- Goz mask + ever smoking bottle = constant fort saves to all non-party members.
- Metamagic Rod of Maximize + Storm bolts + Quicken Material components + 1 level Sorcerer = take 40d8+40 Fort Save for half.

You could make all the monsters start invisible. Having a party of players all slap their heads because they can't see invisible creatures in priceless.
I mean, maybe they will all have some good buffs and magic items to help them see invisibility, but I bet at least one of them will be out of luck in the first round. It doesn't even have to be improved invisibility, just a one-shot for you to giggle at. You need to have fun here, too!
Battlefield control can be key--monsters that can move in different ways can make for a tense fight. Burrowers, incorporeals, even a monster protected by some water hazards or high winds (makes ranged attacks a little tougher without some abilities).
This is almost a weird bending of the rules, but polymorph any object can set your creatures to have different types than the players expect (anyone feel free to correct me if I am way off). For example, a golem polymorphed into a manticore still retains the construct type. A bear polymorphed into a black pudding can still have animal growth cast on it. It's cheese, absolutely, but a cheese of a slightly different smell. This might have been errata'd in the last few years though.
I would personally retain a small army of goblins with tanglefoot bags and other cheap touch attack effects to make some random fun. It gives you a round of battlefield control and gives them a big group of cheap minions to blast. Sure, there are a lot of easy ways to avoid these things, but sometimes very low-level tactics can be fun (or just a distraction). Many 1st-level spells are dangerous in mass, but don't pound someone with eighty magic missiles. Maybe seven of them a round, but not eighty.
Got a few slightly higher level wizards? Encase someone in a few walls of stone or ice. Splitting the party even momentarily can make it tense. Doesn't have to be lethal, just take a few actions away from them.
Illusions are fun, just don't overdo it. At this high of a level, it is almost guaranteed the spellcasters will know exactly what spells you are casting all the time if they can see or hear you (unless they are still and silent spells), so making illusory monsters is rather difficult, but you could always make it obvious and then have another monster teleport into the "illusion" group.
Just a few suggestions on how to maybe add a little spice and fun to the arena.
