Pun-Pun: sarrukh out of savage species can add/remove/set ability scores and special abilities. Using a +1 la template that grants 11th level wild shape and assume supernatural ability pun-pun takes advantage of this before most wizards cast polymorph.
The Omniscificer: by pretending there are no rules on how to stack effects you manifest several share pain powers so when you're dealt 8 damage you echo two 4 point totals to them whom in turn echo another two sets of 2 back to you causing you to echo two iterations of 1 damage back to them and OMG SQUIRREL! and that's how it's a none diminishing return and infinite then you just use masochism to gain a skill bonus based on damage received.
The Terminator: a repost of the same game trick which is about psionic nomad that manifests time hop on a fission sending it into the future then the slave manifests a quickened divination to gain some intel and then use time regression to return to just before it's previous turn, drastically outdone by using quintessence to send something into the heat death of the universe.
The Wish & The Word: it just wishes for more wishes and observes that with a high enough caster level blasphemy can drive none-epic none-evil creatures just as equally as it can get a group of nuns to walk away form you.
Chicken Infested Commoner:
The Jumplomancer: the exemplar can make a lot of skill checks using his diplomacy bonus, including escape artist, and this build forgets left and right are not the same thing half way through and thinks you can make diplomacy checks using your jump bonus from speed.
The (Tauric) Hulking Hurler: this is what happens when your dm allows you to apply the same template six hundred times and then ignore the la because the tauric template's +4 is taken to mean =4.
Bubs: optimized handle animal bonus can theoretically turn you into a pokemon trainer if they don't eat you.
The Twice-Betrayer of Shar: it's a cleric of mystra that uses reach spell to modify touch spells into having a fixed range for persist spell and then overlooks how ocular spell doesn't change the range on the spell cast until after it's fired later.
Nanobots: 200 tiny creatures can share the same space and there are twenty six adjacent spaces next to you, now imagine what the aid other action can do for you.
Chuck E Cheese: by overlooking the fact that footsteps cannot be persisted you generate a large movement speed and use tornado throw to convert movement into damage as exactly as the maneuver tries to tell you to do.
The Emerald Legion: if mind flayers could craft custom magic items without xp costs and given free roam to apply templates they would probably copy Hitler's eugenics program with stuff like half-clay weredire air terrasquaes or something.
The d2 Crusader: pretends the luck domain's ability to set a result of '1' to a '2' actually alters the face that a die so stance of chaos can deal infinite damage.
H.I.V.E: it's just a build that realized vermin lord lets you become lord of the flies as a sorcerer with a huge charisma score which is pretty much what it was expressly designed to do.
The Shepherd, The Saint, and the Sinner: it's just a build that realized D&D is a multiplayer game where a collective group of the standard four adventurers can share resources, so it used thrallherd to gain leadership instead of asking anyone to play because unnecessary convolution is a goal of optimization.
A bunch of random names: out of boredom someone asked if can you achieve a bunch of 100s for like two minutes a day and called it 100^10 because math was not their strong point, and by casting a lot of spells/powers these build probably, I mean no one actually reads them anyway, did it.
Cheater of Mystra: overlooks the fact that in a church of mystra a cleric gets free matamagic anyway to tell you how get a couple extra turn undead uses for divine metamagic with a minor tangent on how dweomerkeeper ignores material components.
The Lightning Thief: outdated rules text in the phb says you can steal stuff as a free action so just steal your self to move around because only a dm can limit your number of free actions per round and we never play with those.
The Basketweaver: the inspiration for this post, it just sits there making baskets as satire of all the I'm-special bs flying around.
The Dream of Metal: an actually very well made and flavored out post that salvaged GitP's reputation that explores what I said about the terminator.
True Dilettante: using embrace/shun the dark chaos and by reading any post listing where to obtain extra feats this thing gets extra feats.
"Festering Anger Lad": it's not even a build, more like someone's quote on a ten year old "trick" called how to heal ability damage combined with festering anger's ability to turn every hulking hurler post into unnecessary spam.
Monty: how to become pun-pun by using plagiarism instead of manipulate form, aka first pass at updating outdated TO.
Tripple Cheesebuger with Onions: it's what happens if you don't read the ardent or southern magician entry, or your spellchecker, and want to achieve three different sources of 9th level casting without using an accelerated-casting class.
Triple 9's: the above but lampshades cheese and uses accelerated-casting but still forgot illthid savant does the same thing without having a human claim he's a blind floating eyeball.
New World Record Mount Familiar Companion by HD: I'm not even sure what this is supposed to be, pokemon ruby's rererelease?
Jovocian Bomb: jovocs from the second monster manual have a super share pain effect that cannot self-target, by getting around that say by stealing the supernatural ability for a bit, you can produce an actual working solution for the omniscificer.
Supermount v1, 2, 3, and so on: watch as people show off their breeds and attempt to win best in the show.
Sleeping Raven Infinite Blood Frenzy: I'm not sure to call this using the stance blood in the water as everyone thought of when they seen it or chicken infested with the stance instead of consumptive field, the latter might at least be worth posting in a fun find thread so I guess I'll call it that.
Uberchargers: if you can't build one, you should read a list thread.
Clone Army: if body outside a body creates a fully stocked resource you can abuse then you can spend it's xp to cast wish.
World Record for Rebuke: what happens if you read a list thread.
Maximum SA possible (per hit): what happens if you read a list thread.
Maximum Eldritch Blast Damage per hit: by illegally retroactively applying legacy champion and claiming la-buyoff applies to none-la levels you can gain an extra eight virtual levels of helfire warlock, except if only applies the bloodline benefit to hellfire and not the legacy champion (or unmentioned uncanny trickster) which means it deal less than other builds that are considered none-TO.
The Maximum Hit Point Tank: necroincarnate's harvest soul is the incarnum version of of the chicken infested trick that runs slower than using shambling mound and uses heart of incarnum to gain a hit point for each of kill-fed essentia pool increase it obtains.
Maximum Skirmish: at least they dug into dragon magazine for resources rather than reading a list thread.
A Full CoDzilla including a maximum turning pools option: it uses a dm provided artifact called the deck of many things and assumes it produces exactly the cards you like by being a trick shuffler in real then throws the word cleric around for some bonus association.
The MAXED +1sorc casting non-ascended, Non-epic Demilich kobold: pretends you can buy off +8 la pre-epic and each time you buy off a point you are treated as being able to buy off the next one immediately as if you were say a +7er opposed to what the text does say and somehow only takes that logic as far as demilich rather than every template ever.
The Ultimate Bear Build: it's just a
anthropomorphic black bear dire bear wildshaped bear
druid / bear warrior with bear puns which is pretty unbearable. It's just a grizzly thread so be prebeared to bear with it.
