Petting the Dragon
After purchasing Pet the dragon, Krumblor can be pet by clicking its icon. If leveled up beyond level 8 (after sacrificing 100 farms), there is a 5% chance to drop an upgrade for every pet.
The next upgrade dropped upon petting is picked like so:
- Shuffle list of available drops
- Pick a drop in the list based on time in minutes
- If minutes are 0 - 14, first upgrade is dropped
- If minutes are 15 - 29, second upgrade is dropped
- etc
Since the shuffle is based only on the game seed, to get all four drops, it is necessary to pet the dragon every quarter of an hour.
The 5% chance is not affected by upgrades and effects that change random drop rates.
Strategy
Two comprehensive Krumblor guides: pastebin and google docs
If a player is going for the overall highest CPS boosts with auras, a combination of Breath of Milk, Elder Battalion, and Radiant Appetite will produce the largest CPS increase (the combination of two that produces the largest increase depends on the player's current progression in the game, see below). If a player is going for harvesting as many sugar lumps as possible, they should use a combination of Dragon's Curve and Reality Bending, as it reduces the maturation time and increases unusual lump rate the most.
This image shows the multiplier for the Breath of Milk dragon aura, based on the milk percentage and which kitten upgrades are active. The bottom line is the base multiplier, the next lines are the multiplier with Mokalsium, Mother Spirit at 5% or 10%. The lines for each kitten upgrade assume that all previous kitten upgrades are active as well. The base line assumes Santa's milk and cookies has been bought, but the 1.05 milk multiplier of Santa's milk would equal Mokalsium, Mother Spirit at 5%.
Using the Dragon's Cursor is not recommended, as if you have even just one mouse upgrade, Breath of Milk will usually improve your CpC (cookies per click) by more than 5% indirectly by increasing CpS (cookies per second), and Radiant Appetite will flat out double CpC through the CpS buff.
With optimal building distribution, Elder Battalion will give an overall very early game production increase of about 1%. The power of this aura will be minimal until you approach 12,000+ buildings owned and after purchasing "Elder Pact", where it will start to dramatically outperform Radiant Appetite. The aura's power will afterwards start to slowly decrease as one unshackles more buildings past fractal engines. In addition, the aura can be used to quickly obtain the achievements that require the player to bake a certain amount of cookies with Grandmas quicker, due to having a larger general CpS buff to grandma CpS than most other auras (although this is mostly irrelevant). However, this should not be used with Godzamok due to a decreased efficiency from selling buildings except for some cases .
Reaper of Fields gives naturally spawned Golden cookies a chance to yield Dragon Harvest, which multiplies CpS by 15 (17 with Dragon fang), and has a chance of ~6.2%. It may be added on top of frenzies through Dragon Orbs or stacking frenzy duration so that another golden cookie (and perhaps one after that) may be stacked with it.
Earth Shatterer should be used before selling all buildings and using the Chocolate egg, since Chocolate egg gives 5% of the current amount of cookies in bank. However, note that selling buildings do not increase the Cookies baked all time stat, so it does not increase prestige either - aside from if the sell makes the amount of cookies in bank exceed the Cookies baked this ascension stat.
The overall effect of Dragon God scales up to 5% with Prestige, as shown in this image on a log scale. Its full potential (of +5% CpS) is reached at approximately 900.7 quadrillion prestige. It should not be used for CpS.
Master of the Armory and Fierce Hoarder may be slotted whenever buying upgrades or buildings.
Arcane Aura is used to increase golden cookie spawn rates while being unable to perform DO ASS CLGCF, and stacking golden cookies for combos.
Dragonflight gives naturally spawned Golden cookies a chance to yield Dragonflight, which multiplies click power by 1111 (1223 with Dragon fang), and is about twice as common than Click Frenzy with a chance of ~6.2%. However, unlike Click Frenzy, it can never be gotten from the Grimoire, where Click Frenzy can be gotten with a 25% chance from successful casts of Force the Hand of Fate. Optimally, one would slot in this aura whenever clicking naturally spawned Golden cookies, then instantly swapping it to another (most likely CpS increasing) aura afterwards. Note that there are several restrictions on Dragonflight (the buff). Most notably, it overrides Click Frenzy at a 80% chance, and prevents Force the Hand of Fate from giving out Click Frenzy whenever it is active. In addition, Click Frenzy from naturally spawned Golden cookies are 20 times less common while it is active.
Ancestral Metamorphosis and Unholy Dominion only affect Lucky, Chain, and Cookie Storms. The benefit of Ancestral Metamorphosis is best utilized from slotting it when Lucky will cap at a percentage of bank and right before a chain breaks (although this may make the reward under 6 hours of CpS).
Epoch Manipulator is used for stacking buffs along with arcane aura. It is recommended over arcane aura because the increased time makes combo execution easier.
Mind over Matter is used for grinding seasonal upgrades and garden drops.
Radiant Appetite has a flat 100% bonus to all production. It easily produces the largest boost in production out of all almost the auras, with exceptions including Elder Battalion and Dragon's Fortune, which may sometimes produce more than it.
Dragon's Fortune can grant a multiplier of over 2 with just one golden cookie on the screen. This can be coupled well with Force The Hand Of Fate, as its multiplier can stack up extremely quickly without bound, resulting in a CpS multiplier of x5, x11.1, and x24.7 with 2, 3, and 4 Golden Cookies on screen, respectively. It is often used in conjunction with strategies such as Force The Hand Of Fate dualcasting or quadcasting to provide a large boost during combos.
Dragon's Curve only affects sugar lumps, but they can be used to buy various improvements. See sugar lump strategy.
Reality Bending has many effects, and may depend on the 2nd aura. Its effect is additive with the second aura.
Dragon Orbs can be used to very quickly kickstart an ascension through forcing combos without any of the primary Golden cookie upgrades, as well as making getting buff stacks easier. It can also be used to obtain Easter eggs quickly, as well as increase Golden Cookie Clicks faster (the spawns do not increment said stat, but Cookies Chains from these spawns force the next natural spawn to be a Cookie Chain, which results in more Golden Cookie Clicks due to the elevated chance for Cookie Chains).
Supreme Intellect gives the following buffs to minigames:
- Garden plants age and mutate 5% faster
- The Stock Market is more chaotic
- The jade slot of the Pantheon behaves as a ruby slot and the ruby slot behaves as a diamond slot
- Spells from the Grimoire are 10% cheaper but backfire 10% more
Supreme Intellect may be used to make plants age and mutate faster, although this may unbalance growth and gives less time for the plants to mutate. The stock market becomes faster paced, making the grind to Gaseous Assets faster. Boosting the pantheon swaps may be used to optimize certain grinds such as using the wrinkler spawn rate buff from Skruuia and golden cookie frequency buff from Selebrak at the same time. Assuming that Selebrak is in the ruby or jade slot, it may be swapped in every single Reindeer spawn to utilize the reindeer frequency and biscut drop rate buff. The cheaper grimoire spells may be utilized with special quadcasting strategies. The increased backfire chance may cause some spells to backfire. This may be used to get Elder Frenzy from an otherwise impossible position. It may also be used to find the backfire rate range of certain spells (eg. if a spell needs Supreme Intellect to backfire, then the backfire range is between 0.835 and 0.85).
Dragon Guts increases the bonus cookies generated by popping Wrinklers and increases the maximum amount of Wrinklers. When it is considered that its 20% wrinkler pop stat can be utilized independently and without having it on passively (by slotting when popping wrinklers, akin to Skruuia, which frees up a slot to slot another CpS aura), it provides an overall idle CpS increase of approximately 60% (fluctuates ~5%), making it inferior to Breath of Milk. If that is not considered, it is almost comparable to Radiant Appetite and Breath of Milk in terms of idle CpS, having a CpS increase of approximately 90%. Note that due to its Wrinkler cap increase, it also slightly increases Wrinkler spawn rate, so swapping between Dragon Guts and an aura that boosts random drop chance will finish Easter or Halloween faster.

Notes
- ↑ Sacrificing grandmas fulfills the unlock condition of the "Just Wrong" achievement.
- ↑ 2.0 2.1 Having the aura Reality Bending active alongside this aura doesn't improve the chances of the golden cookie outcome.
- ↑ This upgrade affects the effect duration of Golden and Wrath cookies, and not the on-screen duration.
- ↑ This affects garden upgrade drops, eggs during easter, and flavored seasonal cookies from Halloween and Christmas.
- ↑ This does not include the golden cookies created by a cookie storm.
- ↑ The minigame information can be accessed via a dragon head icon (
) under each minigame. Reality Bending does not display information boxes when selected alone, but it does provide a boost as long as Supreme Intellect is unlocked. If both auras are selected, the values in the information boxes change accordingly.
Trivia
- Krumblor will always appear below Santa.
- The left slot for Krumblor is considered the secondary aura slot, while the right slot is considered the primary aura slot.
- Krumblor makes a cameo appearance in AdventureQuest Dragons, another game made by Orteil in conjunction with Artix Entertainment.
- If the player has no buildings, there is no cost for switching auras.
- It takes a minimum of 4.98202195202296e+39 (4.98 duodecillion) cookies total to complete Krumblor's training.
