Unstable Concoction (BTDB2)

- BTDB2 description

Unstable Concoction is the 3rd upgrade on Path 2 of the Alchemist in Bloons TD Battles 2. It is similar to its BTD6 counterpart, except it is more expensive, in addition to soaking concoction into all layers of blimps. Concoction potions coated onto blimps are now green to distinguish from purple acid from Stronger Acid.

It costs $4000.

Summary
Unstable Concoction is extremely potent at dealing high damage but is also extremely unstable for low-end devices, especially smartphones and "potato" PCs.

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.
