Monkey Knowledge main menu as featured in Version 1.0.1, featuring 6 categories of upgrades

Monkey Knowledge is an enhancement system in Bloons TD 6 that allows the player to unlock incremental improvements for their towers. There are 6 different upgrade trees for Primary Monkeys, Military Monkeys, Magic Monkeys, Support Monkeys, Heroes, and Powers. Each tree features many different upgrades and perks that can be unlocked with Monkey Knowledge Points.

Starting from Level 30, almost every level up will reward the player with 1 Knowledge Point to use. Some upgrades require a certain amount of points to be spent in the tree before being unlocked and are lower on their tree. Previous upgrades have to be unlocked to unlock upgrades further down the tree that are more powerful. More Knowledge Points may be earned through achievements, and it takes 134 points to unlock all of the upgrades. The total amount that can be earned (by reaching level 155 and getting all achievements with Knowledge Point rewards) is actually 137.

It is possible to immediately reach Level 30 by going to the Monkey Knowledge menu and buying the purchase that unlocks Rank 30 immediately to start earning Monkey Knowledge. However, it costs $9.99 USD, and level 30 can often be reached very quickly so it is generally not advised. A single Monkey Knowledge Point can also be purchased for $0.99 USD.

Monkey Knowledge can be toggled on or off. This can be helpful for testing towers or for practicing C.H.I.M.P.S. mode. A respec option allows the player's Monkey Knowledge to be reset for a cost of BloonjaminsIcon2,000. Using this will refund all spent Monkey Knowledge Points so players can assign them to other Knowledge, and any Monkey Money invested in a Knowledge Point does not need to be reinvested.

In Version 15.0, a change was made where the fourth row of upgrades and further would also require Monkey Money to be purchased. This was done to balance out more powerful Monkey Knowledge upgrades and force the player to either consider buying the Monkey Knowledge point or save up their Monkey Money for other purposes.

The Monkey Money requirements for each knowledge point increases per row, with the fourth row of points costing BloonjaminsIcon250, the fifth costing BloonjaminsIcon500, and the sixth costing BloonjaminsIcon1,000. Subsequent rows are fixed at the same price as the sixth row. Unlocking Monkey Knowledge points from the lower rows of a tree after purchasing a respec will not charge Monkey Money if those points had been unlocked previously.

Knowledge Rewards[]

It costs one Knowledge Point to access a new upgrade. For further upgrades, it may require a specific number of points already invested in that tree before unlocking the upgrade, so note them in the tables.

(The "Requires X Points" statement can be ambiguous. It means that a certain number of Monkey Knowledge must be invested in a specific Monkey Knowledge group in order to unlock the upgrade that requires X points, not that it can be unlocked upon the Xth investment into the specific Monkey Knowledge group. For example, "Requires 3 Points" means that there has to be at least 3 Monkey Knowledge Points invested above the displayed requirements line.)

Strategy[]

Summary[]

Strategization of the Monkey Knowledge system involves progression in general gameplay. To accumulate Monkey Knowledge Points quicker, level up faster to earn more Monkey Knowledge Points, or achieve some Monkey Knowledge Points via certain Achievements. Some Monkey Knowledge at the top of the trees provide significant advantages in terms of unlocking the game's full potential, some examples being ExtraDartsPopIcon Extra Dart Pops (+1 Dart Monkey pierce) and MoMonkeyMoneyIcon Mo' Monkey Money (+10% MM per game). Eventually, the player will need to plan ahead to access the powerful MK at the lower branches of the tree as efficiently as possible. Take note that additional requirements are necessary to access deeper Monkey Knowledge.

Early MK[]

The following are a selection of tips about unlocking Monkey Knowledge near the top of the MK Trees, as well as players who only recently unlocked Level 30 and above.

  • ExtraDartsPopIcon Extra Dart Pops: The bonus pierce greatly assists early-game Dart Monkey strategies, thanks to the +1 pierce for a very cheap tower. Also extremely helpful on Half Cash with 0-0-0 Dart.
  • NavalUpgradesIcon Naval Upgrades: Like Extra Dart Pops, the bonus pierce greatly assists the general power of Monkey Subs and Monkey Buccaneers. Naval Upgrades is helpful for these water towers, as both of these options heavily involve projectiles with low pierce but many quick projectiles. Also extremely helpful on Half Cash with 0-0-0 Sub.
  • LingeringMagicIcon Lingering Magic: In addition to progressing towards many of the stronger Magic MK, Lingering Magic's projectile lifespan increase helps increase the uptime of Wall of Fire.
  • MoMonkeyMoneyIcon Mo' Monkey Money: All players, especially newer players, should utilize this MK to maximize Monkey Money generation from normal gameplay of the game. To unlock it, LingeringMagicIcon Lingering Magic and SpeedyBrewingIcon Speedy Brewing are required in that order; it takes up to 3 MK Points to unlock MoMonkeyMoneyIcon Mo' Monkey Money.

Middle MK[]

The following are a section of tips about unlocking Monkey Knowledge around the middle of the MK Trees.

  • MasterDoubleCrossIcon Master Double Cross: The capability to place a second Crossbow Master enables any MK-enabling game mode to use that second Crossbow Master for further DPS, and in the case of Boss Bloon Events it accesses an easy way of obtaining a Degree 22 Apex Plasma Master instead of Degree 1.
  • BiggerBanksIcon Bigger Banks: It increases bank capacity by $2500, which enhances Monkey Bank strategies. Waiting an extra round or two for an already high amount of stored cash is advantageous for maximizing income gain from Banks.
  • HeroFavorsIcon Hero Favors: It reduces base cost of Heroes by 10%, making them more accessible for the early-game, allowing for an easier headstart to leveling up.

Late MK[]

The following are a section of tips about unlocking Monkey Knowledge towards the bottom of the MK Trees, as well as once an excess of MK Points is obtained:

  • BonusMonkeyIcon Bonus Monkey! and MoreCashIcon More Cash: These are among the most important MK to obtain in the Primary MK Tree. With these MK, the extra savings in the early-game widen the diversity of starting options.
    • It takes a bare minimum of 15 Monkey Knowledge Points to unlock "More Cash" in the Primary MK Tree. One possible method to do so is to purchase Fast Tack Attacks, Increased Lifespan, Extra Dart Pops, Fast Glue, Crossbow Reach, More Splatty Glue, 4 And 4, Cheap 'Rangs, Aviation Grade Glue, Master Double Cross, Cheaper Solution, Come on Everybody!, Bonus Glue Gunner, Bonus Monkey!, and then More Cash in that order.
  • MilitaryConscriptionIcon Military Conscription: Discounting the first Military Monkey by 33% enhances early-game strategies involving Military Monkeys.
  • BigBloonSabotageIcon Big Bloon Sabotage: It is helpful in general gameplay and extreme late-game runs by decreasing some HP from the outer layers of MOAB-class bloons, especially BADs.
    • It takes a bare minimum of 15 Monkey Knowledge Points to unlock "Big Bloon Sabotage" in the Military Tree.
  • ManaShieldIcon Mana Shield: Mana Shield protects a few leaking lives outside of Impoppable (and obviously outside of CHIMPS).
    • It takes a bare minimum of 9 Monkey Knowledge Points to unlock "Mana Shield". One possible method to unlock it is to purchase Lingering Magic, Magic Tricks, Speedy Brewing, Mo' Monkey Money, Hot Magic, Flame Jet, Arcane Impale, and then Mana Shield in that order.
  • BankDepositsIcon Bank Deposits: Bank Deposits assists in maximizing income gain from IMF Loan via the Bank Deposit functionality.
  • HealthyBananasIcon Healthy Bananas: Earning extra lives from Marketplaces and Central Markets allows for generation of lives without need to activate abilities.
  • EmpoweredHeroesIcon Empowered Heroes: This is an important MK for leveling up Heroes immediately to Level 3 for a large headstart.
  • Unless on a glut of MK Points, avoid most Monkey Knowledge in the Power MK Tree, with exception of PregamePrepIcon Pre-Game Prep.
  • PregamePrepIcon Pre-Game Prep: Upon starting each game, automatically places Road Spikes at all exits. This is very helpful on Impoppable in particular, since ManaShieldIcon Mana Shield is banned on that game mode.
  • ParagonOfPowerIcon Paragon of Power: Allowing a Paragon to attack substantially faster without additional T5’s of that same tower type is a powerful asset for MK-enabled Boss runs in particular.

Disadvantages of MK[]

Monkey Knowledge can occasionally introduce new challenges with strategization. Some of these MK Points require adaptation to retain a net advantage of the unlocked MK Points.

Certain types of Monkey Knowledge Points are strictly disadvantageous for some types of strategies. Depending on specific strategies involving Monkey Knowledge, certain MK Points may be harmful for strategies. Some MK Points can be avoided completely, but some are inevitable in the progression towards stronger MK, and already unlocked MK Points cannot be manually turned off individually.

  • BigBloonSabotageIcon Big Bloon Sabotage: This MK lowers the outer layer HP of MOAB-class bloons by 10%, which can be disadvantageous for accruing maximum pops for Paragons. Competitive Ranked Boss Players are advised to use the Respec button to manually turn off this MK, allowing to-be Paragons to gain maximum pops.
  • TargetedPineapplesIcon Targeted Pineapples: Targeted Pineapples changes the location of pineapples to only target tracks, similarly to Bomber Ace. For some players, the specific timing of pineapples landing erratically is superior to only targeting tracks, as the pineapple locations without this MK become more consistent with the timing of the Ace's movements, rather than the positions of the nearby track. Unfortunately, as Targeted Pineapples is a prerequisite of deeper Ace-related MK, this MK cannot be feasibly avoided.
  • WingmonkeyIcon Wingmonkey: The added Wingmonkey targeting option is considered by some players to be a nuisance to Ace micro, as the unpredictable nature of the eponymous targeting option can interrupt the positions of Aces.
  • AcidStabilityIcon Acid Stability: The longer acid pool lifespan may worsen income generation from Rubber to Gold, as the extra puddles eat up more bloons that could have been coated with golden potions. However, it could be somewhat more useful for Lead to Gold's lead income generation, as the extra pools allow more opportunities for this Alchemist to pop Leads. As Acid Stability is not a prerequisite of any other MK, it can be turned off.

Additional Tips[]

Version History[]

Trivia[]

  • It costs a total of BloonjaminsIcon33000 to unlock all Monkey Knowledge as of version 30.0.
  • The Engineer Monkey was the icon for the support tower knowledge even before it was added to Bloons TD 6.
  • "Big Bloon Sabotage" is the same name of the Monkey Lab upgrade in Bloons TD 5. It retains a similar effect, reducing the health of the MOAB-class bloons.
  • In order to obtain all upgrades for all the categories of Monkey Knowledge, the player must achieve Level 155, assuming that no extra packs have been purchased or earned from achievements or other sources.
  • "Weak Point" is the only Monkey Knowledge that requires all other Knowledge in the tree in order to unlock it.
  • "More Cash" is the most expensive Monkey Knowledge in the game, requiring a total of BloonjaminsIcon4,500 invested in the Primary tree to unlock.
  • It takes a bare minimum of 14 Monkey Knowledge Points to unlock "More Cash" in the Primary tree.
    • One possible method to do so is to purchase Fast Tack Attacks, Increased Lifespan, Extra Dart Pops, Fast Glue, Crossbow Reach, More Splatty Glue, 4 And 4, Cheap 'Rangs, Aviation Grade Glue, Master Double Cross, Cheaper Solution, Come on Everybody!, Bonus Glue Gunner, Bonus Monkey!, and then More Cash in that order.

  • The "Naval Upgrades" Monkey Knowledge essentially turns the Monkey Buccaneer's main dart attack pierce and grape pierce to what it was in BTD5: 5 pierce per dart, and 2 pierce per grape.
