Unstable Concoction is the 3rd upgrade on Path 2 of the Alchemist in Bloons TD Battles 2. It adds a new concoction attack to the Alchemist's arsenal. In terms of functionality for its new concoction attack, it is similar to its BTD6 counterpart, except it is more expensive. Additionally, all concoction effects coated onto blimps are now green to distinguish from purple acid from Stronger Acid.
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, dealing damage equivalent to 10% of its health to other blimps or 1% to bloons, without taking into account Freeplay health scaling. Unstable potions are thrown every 6.0s (every 4.8s with Faster Throwing), have 3 pierce each, and a splash radius of 14 units (21 units with Larger Potions). Larger Potions does not increase pierce of these unstable potions. This additional concoction attack also has increase 50% attack range compared to alchemist itself.
Concoction explosions have a blast radius of 40 units and affect up to 30 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.
It costs $4,000, and is unlocked with the purchase of Alchemist.

Summary[]
Unstable Concoction is extremely potent at dealing high damage but can cause a lot of lag on devices like smartphones and low-end PCs. Make sure you have good PC specs otherwise this upgrade might just crash your game.
Tips[]
- 0-3-1 Concoction is usually better than 1-3-0, as the pierce from 1-3-0 doesn't actually work and 0-3-1 offers more attack speed for concoction potions. Tier 2 upgrades can be added to support other functionalities of the Alch but are irrelevant for Concoction.
