Best Tier-5 Upgrades in Bloons TD 6
Tier 5 upgrades are a new addition to the popular BTD6. They are usually very expensive, but mega powerful.
Even after the nerf, it is still able to destroy an ENTIRE B.A.D. with Monkey Village and Alchemist support.
The tier 5 upgrade of the third path of the spike factory, the Perma-Spike, was the unanimously the most overpowered upgrade in the entire game before update 2.0, when its fire rate was decreased drastically. this upgrade sends out piles of 50 spikes which do 10 damage each. These spikes will carry over 4 rounds, giving it its name. It used to cost 20000, but the price was increased to 25000.
This is literally the best towers, you can regen farm with this easily, allowing massive income and even more money, it can literally destroy the hardest bloon on screen. DDT's a problem? Heres the solution.
just overclock it, perma-brew it, and Homeland defense and your set for round 100
Anyone who disagrees is flat out wrong. It is better than supermines yet costs just a fifth of the price. They nerfed it multiple times but it is still op.
Is able to obliterate a entire BAD if used correctly.

The tier 5 upgrade of the first path of the wizard monkey, the Archmage, is known to be one of the most powerful upgrades in the game. It attacks much faster than it's previous upgrade, arcane spike, and its attacks do a whopping 25 damage to M.O.A.B.s and higher. On some tracks, it can even destroy an entire Z.O.M.G, children and all, by itself. That's not bad for a tower that costs 32000.
Combine with Comanche Commander for an incredibly powerful two-man defence that can easily defeat a ZOMG.
Just a beast for chimps
Best wizard path because of dragon's breath and shimmer added

The Tier 5 Upgrade of the first path of the boomerang monkey, the glaive lord, isn't really known to be a bad-ass by most people, but they can pretty much destroy an infinite amount of B.F.Bs. In BTD5, it was kind of overpriced, but not anymore.
Really strong and cheap
Bloons worst nightmare
This version of glaive lord is much better than the BTD5 version

This thing makes money for free and you can use the money it makes to buy more banks and make more money and it's even better then BIA form bad 5 which is better then loan by the way.
The tier 5 upgrade of the second path of the banana farm, monkeynomics, will give you a lot of money. If you need quick cash in the late game, you can use druids, but if you can afford it, get this. For $100000, you'll get an ability to GIVE you $10000. just use it 10 times, and you've got your money back. sure, you could get a lot of druids, but those take up space.
It may be expensive, but Monkeynomics is a great example of stonks.
It makes a lot of money!

The tier 5 upgrade of the third path of the alchemist, the Bloon Master Alchemist, can easily turn any bloon up to a B.A.D. into a red bloon. That's right, ANY bloon up to a Z.O.M.G. can be transformed. He's not that slow with it either.

The Tier 5 upgrade of the second path of the druid, the spirit of the forest, does multiple things. It's main use is to do damage to everything on screen several times, being able to destroy pre-round 81 ceramics, but that's not it. It also gives you 25 lives and $1000 every round. Combined with its previous upgrade, jungle's bounty, you'll be making money really quickly. Not bad for a $50000 upgrade.

This should be higher. Pretty costly, but it will ELIMINATE ddts, and leave fortified ddts with 50 health. And that's not to mention the ability, instakilling everything up to a BAD
The Tier 5 upgrade of the second path of the monkey sub, preemptive strike, is a free ticket to defeating one of the hardest rounds in Impoppable and Chimps modes, round 95. This round has a rush of D.D.T. bloons, but they're no problem for this tower. In earlier free play rounds, the preemptive strike sub will destroy all M.O.A.B. and D.D.T. bloons, no problem. The reason its not higher is due to it's use going down in higher rounds.
Can Destroy BAD alone. Ability wrecks BADs and this can make it so there is no remains of a BAD
Can wreck everything

One of the best rank 5 upgrades. Just awesome (if a bit expensive) shooting a salvo of darts and bombs at hypersonic speeds. Shreds all diffcultes.
The tier 5 upgrade for the third path of the monkey ace, the flying fortress of bloon doom as I like to call it, is extremely powerful. It shreads M.O.A.B. class bloons with relative ease, able to do major damage to B.A.D. bloons. Why so low, then? The reason is its price. The flying fortress costs a whopping $120000! More than a temple! My point has been made.
Heat seeking bomb so fast and loss them.

This should be #2 or #1 you can get the dark vengeful temple and glitch it so the balloons cannot be even seen.
True Sun God and especially the Vengeful Temple and Solo long after round 100 and beyond.
How could we have this list without the most destructive upgrade of them all? The true sun god isn't higher on the list due to its price, coming in at a whopping 500000!
It destroys everything, but expensive so not easy to use in most games.

Dude this NEEDS to be higher. It shoots w infinite range, dealing 200 damage to MOAB's, with huge pierce. Not to mention giving primary monkeys tier 1, and 2 upgrades for free, saving lots of money.
The Tier 5 upgrade of the first path of the Monkey Village, primary expertise, isn't really a good upgrade, by its definition. It gives primary monkeys tier 2 upgrades for free. Why not give all monkeys tier 2 upgrades for free? This tower is more than just that, however. It also gains a powerful attack known as "Mega Ballista," which can easily take down M.O.A.B. class bloons. To me, it's worth the 25000.
It isn't the best tower, but getting free tier 2 upgrades is very useful for primary towers, especially cannons.

The tier 5 upgrade for the first path of the alchemist, permanent brew, isn't very useful by itself, since it doesn't give any extra bonus from stronger stimulant, but with the help of a support chinook heli, it can be pretty good. It's a little overpriced in my opinion, though.
This should be higher for sure, PermaBrew provides permanent buffs to other towers making the first 100 rounds basically free.
Very good buff
Absolute crazy fire rate
Easily destroys wave 95
Ability when blooms are going to leak through is op as it can literally take anything

The tier 5 upgrade for the first path of the monkey sub, energizer, used to be useless. It gave water based towers in its radius a quicker cooldown. Now, it's amazing, giving EVERY water tower a quicker cooldown, and halvening the cooldown time of water towers in its radius. Not to mention the hero XP bonus. It also gives a pierce buff to its attack.
Good support tower
Just plain useful
Just does an insane amount of damage. Plus slows bloons down. No reason not to use it.
The bloon solver eliminates moabs instantly. And is strong enough to take down a bfb in a few seconds.
Easily takes 63 and 76
This tower with 20 max shinobis, overclock, and other support towers makes the strategy easier. Though, these things I listed may be expensive.
Beast mode for chimps
The grandmaster ninja with caltrops is insane and can output a lot of damage in a few seconds
The best of them all. With full metal jacket and large caliber, it shoots every 0.05 seconds, with each shot dealing TONS of damage.
When its not hitting bloons, there are no bloons. Seriously, there is no break between shots. It is nuts.
When does it stop? Never!
It may not be the best wizard, but prince of darkness is absolutely insane when combined with a mortar.
Summon your own legion with this!
Overrated, but good
Super mines can instantly destroy a zomg. Just a single super mine spike ball can do extreme damage to a B.A.D, super mines and perma-spike is able to take down a entire bad in a few seconds. No wonder super mines is so expensive
Super mines simply do tons of damage and can destroy literally any bloon.
Overall good tower when paired with more subs.
It may be expensive but is extremely overpowered, it has a variation of attacks, including druid spikes, lightning shock, ball of lightning, super tornado capable on blowing away MOAB class balloons
The buff is great
Easily can solo anything but a BAD with a 4-2-0 Monkey Village, stalls eternally.
