History ThatOneAchievement / CookieClicker

* The final cookie milestone achievement as of version 2.052 is '''And a little extra''', which requires the player to bake 1 trevigintillion (10[[superscript:72]]) cookies in one ascension. By contrast, the last CPS milestone achievement (Speed is the name of the game (no it's not it's called Cookie Clicker)) requires the player to bake only 100 septendecillion cookies per second (10[[superscript:56]] CPS). Most of that income will likely have to come from combining [[LuckBasedMission Golden Cookies]], making the last few cookie milestone achievements some of the most tedious to obtain.

* Some of the "have X of this building" achievements get ridiculously expensive. The worst one as of version 2.052 is '''Introspection''', for having 700 You, which costs duovigintillions of cookies. For comparison, the most expensive You upgrade, "Reading your clones bedtime stories", costs only about 27 unvigintilion, about 1000 times less than it costs to own 700 of said building. By extension, this also makes the final "have X of all buildings" achievement, '''Septcentennial''' equally as difficult, as it requires the player to have at least 700 of every building.

** Golden Clovers are just a slightly more powerful version of the Ordinary Clover, adding 3% to golden cookie spawn frequency over the Ordinary's 1%. It also has the lowest mutation chance in the game, at ''0.07%''.

** Two plants, brown mold and Crumbspore, have a chance of spawning when harvesting mature Meddleweed. Not only are these the only plants that spawn when a mature plant is harvested (as opposed to just spawning next to them when the proper mutation conditions are met and you get lucky), Meddleweed is a completely useless plant that you're likely to just destroy whenever it initially spawns. If you're diligent about keeping your garden free of weeds, freeze your garden before going to bed, and aren't reading a guide, you'll quickly run into a dead end without the fungus crops for further crossbreeding.

* '''Black Cat's Paw,''' the achievement for clicking 7,777 golden cookies. While this has gotten easier since its introduction thanks to things such as the Grimoire [[note]]except that Grimoire cookies don't actually count[[/note]] and Garden letting you speed up golden cookie spawns, and even lost its former Shadow achievement status, this still takes a painfully long time, especially since neither Cookie Chain cookies not Cookie Storm cookies count for the achievement.

* Some of the "have X of this building" achievements get ridiculously expensive. The worst one as of version 2.052 is '''Introspection''', for having 700 You, which costs duodecillions of cookies. For comparison, the most expensive You upgrade, "Reading your clones bedtime stories", costs only about 27 unvigintilion, about 1000 times less than it costs to own 700 of said building. By extension, this also makes the final "have X of all buildings" achievement, '''Septcentennial''' equally as difficult, as it requires the player to have at least 700 of every building.

* Some of the "have X of this thing" achievements get ridiculously expensive. The worst one as of version 2.052 is '''"Introspection"''', for having 700 You, which costs duodecillions of cookies.

* '''"Keeper of the Conservatory"''', and by extension '''"Seedless to Nay"'''. The former is obtained from completing the full seed catalog, while the other is obtained for sacrificing it for ten sugar lumps. Getting all of the seeds is easier said than done, as several of the Garden plants are extremely frustrating to obtain, either due to [[LuckBasedMission extremely low mutation chances]], expensive seeds, slow or inconsistent growth times, or obscure mutation requirements - or in the worst cases, ''all of the above.''[[note]]This ''can'' be mitigated somewhat; the results of a tick are determined when they happen, meaning you can save directly before a tick happens and SaveScum until the desired mutation spawns. In addition, seed costs take CPS buffs and debuffs into account, meaning seeds are half-price during a Clot and almost completely free during Cursed Finger.[[/note]] To make things more frustrating, several plants hurt far more than they help.

* '''"When the Cookies Ascend Just Right"''' requires you to have ''exactly'' one trillion cookies in the bank when you ascend. This achievement requires ''immense'' persistence to get.

* Some of the "have X of this thing" achievements get ridiculously expensive. The worst one as of version 2.052 is "Introspection", for having 700 You, which costs duodecillions of cookies. For comparison, the most expensive You upgrade, "Reading your clones bedtime stories", costs only about 27 unvigintilion, about 1000 times less than it costs to own 700 of said building.

* The four baked cookie milestone achievements added in 2.048 ("Fake it till you bake it", "History in the baking", " What do you get for the baker who has everything"and "Bottomless pit") are all prime examples of {{Last Lousy Point}}s. These achievements are obtained for baking 100 vigintillion, 1 unvigintllion, 100 unvigintillion and 1 duovigintillion cookies in one ascension respectively. By contrast, the last CPS milestone achievement ("I'll rest when I'm dead") requires the player to bake only 1 septendecillion cookies per second. Most of that income will likely have to come from clicking [[LuckBasedMission Golden Cookies]], making these achievements some of the most tedious to obtain.
* '''Any achievement dealing with sugar lumps''', especially the "Years worth of cavities" and "reach level 10 (building)" achievements. Since you gain approximately 1 sugar lump per day [[note]]only a bit more if you consider the chances of getting bifurcated, meaty, caramelized, and golden lumps, and the chance of getting one from a golden cookie[[/note]], it would take a ''[[ExactlyWhatItSaysOnTheTin whole year]]'' to get the former achievement. By the same logic, it would take 55 days to get any of the buildings to level 10. Getting ''all'' of the buildings (of which there are 20 as of the latest update) to level 10 would take 1100 days, a little over ''three years''. Getting the golden sugar lump shadow achievement (which fortunately doesn't count towards milk) has a 0.03% chance of occurring each day, meaning the average amount of time it would take to get it would be ''five years''. With the introduction of Gardens, it is possible to speed things up to an extent - a Juicy Queenbeet produces a sugar lump when harvested, and with a full-size garden and all relevant buffs, you can get around four extra sugar lumps a day on average - doing it this way has its own caveats; see the section below.

While this has gotten easier since its introduction thanks to things such as the Grimoire and Garden letting you speed up golden cookie spawns, and even lost its former Shadow achievement status, this still takes a painfully long time.
