Strategy:Alchemist (BTD6)

This article was last updated for: version 47.0

The Alchemist is a tower primarily used for support purposes. Its main draw are the buffs that the top path can provide that can significantly improve a player's defenses.

Upgrades

Path 1

The top path Alchemist is incredibly versatile and can improve almost any strategy. 2-x-x Acidic Mixture Dip can be useful for cheap lead popping power in a pinch. 3-x-x Berserker Brew and 4-x-x Stronger Stimulant are cost-effective ways to buff almost any tower. 5-x-x Permanent Brew is usually worse than simply having multiple Stronger Stimulants.

The best crosspath depends on the situation: x-2-x Perishing Potions gives the buff a longer duration, and should be used if the Alchemist is only buffing a few towers. When buffing a large number of towers, use x-x-1 Faster Throwing as it allows the Alchemist to throw the buff potion faster. x-x-2 Acid Pool is almost always redundant.

Do not use the top path when fighting Lych: Lych will remove the buff from your towers and heal itself in the process.

Path 2

x-3-x Unstable Concoction is useful for blimp-heavy rounds like 57, 62, and 71. x-4-x Transforming Tonic is underwhelming, and requires support to be usable. x-5-x Total Transformation is expensive, but can be useful in specific strategies with Shinobis or Druids of Wrath (the latter being buffed with Poplusts). Total Transformation also pairs well with Plasma Monkey Fan Club as the two abilities can be combined for 100% uptime.

Unstable Concoction should be crosspathed with x-x-1 Faster Throwing; x-4-x and x-5-x do not benefit from crosspaths.

Path 3

The bottom path Alchemist is generally mediocre. x-x-4 Rubber to Gold can be useful as a cheap money maker. x-x-5 Bloon Master Alchemist can be deadly with proper support, but falls off past Round 100 due to its inability to hit BADs. The BMA also suffers from the same issue as Benjamin's bloon trojan; it severely affects income due to instantly deleting all MOAB-Class Bloons.
