“ | Coats MOAB-Class Bloons in an explosive substance that causes a large explosion when they are popped. | ” |
~ In-game description |
Unstable Concoction is the third upgrade of Path 2 for the Alchemist in Bloons TD 6. This upgrade gives the Alchemist an additional concoction attack that only targets MOAB-class Bloons, applying a concoction status effect that makes it unstable. A MOAB-class Bloon inflicted with unstable splash will create a large explosion when popped. Unstable potions are thrown every 6.0s (every 4.8s with Faster Throwing), have 3 pierce (4 with 1-3-0) each, and a splash radius of 14 units (21 units with Larger Potions). This additional concoction attack also has +50% attack range compared to the Alchemist itself, throwing from up to 67.5 range instead of 45.
Concoction explosions have a blast radius of 40 units and affect up to 50 bloons, but MOAB-class bloons consume more pierce. MOABs and BFBs consume 2, ZOMGs and DDTs consume 4, and BADs consume 10. These explosions can pop any non-camo bloon type, and can affect camos if the original Alch was given camo detection at the time.
This upgrade costs $2,550 on Easy, $3,000 on Medium, $3,240 on Hard, and $3,600 on Impoppable.
Description[]
Overview[]
The Alchemist wears a completely new outfit. It no longer wears a black facemask, but instead closes its goggles and wears a white lab coat with black covered shoes. The Alchemist now carries a purple bottle of chemical concoction alongside the normal potions. There are some purple stains on the monkey's fur, which match the color of the chemical concoctions that would be applied onto blimps.
Unstable Concoction adds an additional attack that coats MOAB-class bloons with unstable chemicals that inflict explosive damage once affected blimp layers have become destroyed. Targets affected by the Concoction status effect are coated in nasty pink chemicals. Each concoction explosion deals a set amount of damage depending on the target.
The damage of the explosions of Unstable Concoction is displayed as follows:
Unstable Blimp | Damage to Bloons | Damage to Blimps |
---|---|---|
MOAB | 2 | 20 |
BFB | 3 | 70 |
ZOMG | 4 | 400 |
DDT | 4 | 40 |
BAD | 4 | 400 |
Boss Bloons | 4 | 1000 |
If the blimp is fortified, the explosion damage is doubled.
Targeting Priorities[]
Unstable Concoction's main attack throws potions in a lobbed arc at bloons according to targeting priority.
- First: Targets the first bloon visible within its range.
- Last: Targets the last bloon visible within its range.
- Close: Targets the closest bloon visible within its range.
- Strong: Targets the strongest bloon visible within its range.
Concoction potions have extended range and follow basic targeting priorities as normal.
Costs[]
- Updated as of Version 41.0. Listed prices exclude external buffs, any sacrifices, and Monkey Knowledge.

Strategy[]
Summary[]
Unstable Concoction fills a supporting role at dealing high damage to blimps through its unstable concoction attacks. Any blimps destroyed while under the unstable concoction status effect will explode, creating a chain reaction that creates multiple explosions on every blimp affected by the status effect. This in effect may spawn large quantities of weaker bloons, which can be used to the defense's advantage or disadvantage depending on how the Unstable Concoction upgrade is utilized. Its greatest usage is on later rounds with hyperdense MOAB-class bloons.
Tips[]
- It is recommended to crosspath an Unstable Concoction Alchemist with Faster Throwing for increased attack speed of the concoction potion.
- Larger Potions will increase splash radius and peirce of the special Unstable Concoction attacks.
- Crosspathing with Acidic Mixture Dip will allow additional support to nearby towers every once in a while.
- Unstable Concoction often transforms dense packs of stronger bloons into lots of weaker bloons. Some defenses strongly favor these conditions, such as Glaive Lord against Super Ceramics (as Glaive Lord has arbitrarily high pierce but deals lots of glaive-spinning damage to nearby bloons), but especially The Bloon Solver. However, some defenses may backfire from these conditions. The player should consider how the overall defense would handle children that exploded from MOAB-class bloons.
- If multitudes of high-tier MOAB-class bloons are more difficult to handle, it is best to set Unstable Concoction on Strong.
- If multiples of lower-tier MOAB-class bloons are more difficult to handle, it is best to ensure all Unstable Concoctions are set on First to target the smaller blimps (which consume less pierce than higher blimps).
- To make the most of this upgrade, this upgrade must be used in conjunction with effective MOAB-class Bloon popping power.
- Unstable Concoction is one of the few effective ways to add rather low-cost support for beating Round 98, the others being Shattering Shells and 2-0-4 MOAB Press spam. There are advantages for using Unstable Concoction over Shattering Shells as with the other way round, but more importantly Shattering Shells will instantly weaken blimps and not leave random clumps of Super Ceramics, unlike Unstable Concoction. However, there is no harm for doing both.
- A MOAB Glue or a Maim MOAB with Shrapnel Shot work well to clump bloons up together for more impactful explosions.
- Unstable Concoction, Ezili and Perma-Spike is an extremely powerful late-game combination; Ezili's high MOAB-class damage pairs well with Unstable Concoction's explosions to break up round 80-100's dense BFB and ZOMG rounds into lots of MOABs and Superceramics, which Perma-Spike can eat up without any issue.

Trivia[]
- Before Version 2.0, which allowed glue to appear on BADs, this upgrade was one of the only that could affect BADs visually. However, as with other MOAB-class bloons, the Unstable Concoction only works when the MOAB-class bloon layer is fully destroyed under the effect of the chemical.
- Unstable Concoction used to be able to damage spawned bloons inside of the exploded MOAB-class bloon (i.e. the exploded MOAB-class bloon can even skip MOAB-class layers), but this no longer works as of Version 3.0.
- It was really useful against the BAD on Round 100, since the explosion from the BAD is so huge that the DDTs are completely popped and the ZOMGs are skipped to BFBs. Obviously though, good BAD-popping power is required to make Unstable Concoction really worthwhile, as the Unstable Concoction alone will not deal enough damage to BADs on its own.
- Unstable Concoction was able to pop Camo Bloons if the MOAB class bloon was near them. This was patched as of Version 12.0.
- This made Unstable Concoction the only upgrade to attack camo bloons without support, as an unsupported Bloon Master Alchemist cannot target camo bloons at all, including splash damage from the bloon-transformation potion.
- Before Version 17.0's percentage damage cap nerf, it was incredibly useful on "epic late-game" Freeplay Mode, as the blimp damage caused by the explosions were able to reach extreme amounts due to the nature of percentage damage and because of freeplay's blimp health ramping.
- In Version 17.1 (and likely also Version 17.0), there was a bug whereby boosting an Unstable Concoction Alchemist's damage via Sun Temple and True Sun God support buffs would allow the Unstable Concoction's explosions to deal extreme amounts of damage.[1] It was highly likely that these explosion damage amounts were just exactly the amount of damage it would have inflicted on Round 150. This was fixed as of Version 18.0, and similarly was fixed for Prince of Darkness and its zombie bloon spawns.
- Several days before then, there was a Black Border Bloody Puddles achieved by u/YouFoundKnowledge on r/btd6 that heavily involved the unstable explosions Unstable Concoction bug.[2]
- Out of all upgrades in the game, Unstable Concoction is the only upgrade to always turn towards the direction of bloons regardless of where the Alchemist is or whether it is attacking or not. Further upgrades do not share this feature.
