what should i focus knowledge on?

[guyrex904]

should i focus all of it on one tree or balance them out or what?

Start with pushing all one tree. Be it Primary or Military first.
Primary will Unlock bonus starting cash which is a HUUUUGGGGEEEE help! Military unlocks MOAB Bloons enter the map Damaged which is always a plus trying to break down one after another.
Then also as a side to work on your Heros Knowledge page is always helpful! Having a good Hero you enjoy to use and work with is always a must in my opinion. Pat Fusty is one of the best to run.

Outside that The 0-2-4 Necromancer Monkey will be your best friend :) That and a 2-3-0 druid.

Good luck out there!

It could also help working on a Knowledge page to boost the towers you use most.
We all play differently and there is no 1 right way to play Bloons and never will. There are so many ways to have a blast :)
Whatever will help you the most. Its how you wanna play.

Because BTD6's economic system is broken and bankrupts the player the entire game, the most important knowledge trees to fill out are the ones that reduce the catastropic cost of trying to play the game.

Primary, is the best,because the final knowledges include an upgrade that gives you extra starting cash (critical to the game) and a free bonus Dart Monkey or Glue Monkey (critical to the game.) without extra cash, the game is nearly unwinnable.

the glue monkey is useless because it can't do damage, but the dart monkey can mean the difference between being able to afford expensive heroes ASAP or having to go without heroes until rounds 20-30. once you get the hero down, it will auto-upgrade itself without precious cash, and give you a fighting chance.


Military is useful because you can get an upgrade that reduces the cost of all militant monkeys by 5%, as well as the first militant monkey costing 2/3rds of the normal price. this can bring some of the cheaper ones (such as the sub and the sniper) down to an affordable amount, allowing you to start a game with 2 monkeys down instead of just 1 (the free dart monkey, and the sub or sniper that costs your entire starting cash if you've unlocked the extra cash boost.)

the Powers skill tree is the worst one by far, but contains the 2nd most useful power up; pre-game Prep. this puts down a few road spikes, effectively allowing you to leak a few bloons early-game without sacrificing precious money.

Support is also worthless, except for Farm Subsidy, which reduces the cost of the first Banana Farm, which is the only way you'll ever be able to afford a farm in the game because they want more than $1500 for it right out the gate and the game is usually over by the time the farm can pay itself back since it will only give you about $40 a round.

Heroes is pretty useful because you can get an upgrade that makes the hero level up more quickly, an upgrade that makes the heroes cost less, and an upgrade that starts the heroes at level 3 (giving you access to the activated ability.) this can mean the difference between leaking bloons and losing the game, or surviving into the rounds 40+.


Magic isn't very good. if you REALLY want to, you can get "Magic Tricks" which reduces the cost of some of the Wizard's early-upgrades to make them actually affordable, and Mana Shield, which can allow you to leak up to 50 bloons if combined with pre-game prep before you lose the game.

I would note that "healthy bananas" knowledge is working against the avatar of wrath's peak damage. Using avatar of wrath you're motivated to keep your lives 100 less than the starting ones, but healthy bananas will give you lives each rounds and thus decrease this difference. The difference that is sometimes hard to get.

Aside from heros starting at lvl 3 and w/e that one for monkey money is, and free dart monke, 2 of the strongest upgrades are the mana shield and roadspikes, simply because they have a snowball effect by allowing you to eco harder or get away with some early game choices that scale better. Likewise any knowledge that reduces the cost of the first of X towers or start with Y bonus is powerful. After those, most mk is honestly just preferences.

You do magic first and get "monkey money."

This one small part of your post makes the rest automatically invalid since it shows your lack of knowledge of the game. But for everyone else's convenience, I read it, and it's mostly random nonsense complaining about upgrade costs with a few bits of basic advice that other people have already said.
