Berserker Brew

"Special brew gives Monkeys extra damage, range, and attack speed. Lasts longer."

- BTD6

Berserker Brew is the third upgrade of Path 1 for the Alchemist. An Alchemist with this upgrade will occasionally throw a potion on a nearby monkey which grants it +1 damage per hit, +10% range, +2 pierce, and +11.1% attack speed (x0.9 attack cooldown). The Alchemist throws one Berserker Brew potion once every 8 seconds. The Berserker Brew potions last for 5 seconds or after 25 attacks (or 6 seconds or after 40 attacks with 3-2-0) from the targeted tower, whichever comes first. The chosen target is the closest buffable tower that does not already have the buff or the buff cooldown. Towers require 5s (4s with 3-2-0) before being able to be buffed again by any Alchemist (only affects Berserker Brew and Stronger Stimulant); cooldown starts as soon as they receive the buff.

Unlike Acidic Mixture Dip, Berserker Brew is always thrown to the tower closest to the Alchemist.

It costs $1060 on Easy, $1250 on Medium, $1350 on Hard, and $1500 on Impoppable.

Description
Berserker Brew allows the Alchemist to throw two different support potions at target towers, a separate Acidic Mixture Dip potion that allows popping of Leads and DDTs as well as deal +1 damage to Ceramics and MOAB-class, along with a new Berserker Brew potion that grants the target tower +1 damage per hit, +10% range, +2 pierce, and +11.1% attack speed (x0.9 attack cooldown). Berserker Brew potions will last for 5 seconds or after 25 attacks from the targeted tower, whichever comes first. Brews are improved with 3-2-0, lasting for 6 seconds or after 40 attacks from the targeted tower, whichever comes first. There is a cooldown of 5.0s (4.0s with 3-2-0) before a new brew can be reapplied to the same tower.

Upon upgrading to Berserker Brew, the Alchemist will gain a wooden barrel on its back, along with a wooden spoon on its right hand. It also gains an orange cloak instead of a purple cloak and orange goggles instead of pink goggles. Upon upgrading along Path 2, it will gain white gloves if upgraded to Stronger Acid or black gloves and black mouth mask if upgraded to Perishing Potions. Upon upgrading along Path 3, its eye goggles will become one single uniform eye goggle if upgraded to Faster Throwing and its eye goggles turn blue once upgraded to Acid Pool.

Summary
Berserker Brew is one of the most cost-effective ways to greatly empower a nearby tower, improving the attack speed, pierce, and damage of the affected towers. In particular, it is one of the best options when paired with towers that attack relatively slowly but possess a high number of projectiles, such as Bloonjitsu, Triple Guns, and Recursive Cluster. The powerful brew effects can be enhanced even further when upgraded to its next upgrade Stronger Stimulant, and the same upgrade provides overall higher brew uptime for most towers.

Tips

 * Berserker Brew is a separate potion from both the main attack and Acidic Mixture Dip. Don't expect that it will always guarantee giving Acidic Mixture Dip to every time it throws potions at the target tower.
 * The best synergies with Berserker Brew are generally towers that shoot high quantities of projectiles but attack relatively slow. Those include: Bloonjitsu, Recursive Cluster, Druids, Grape Shot/Hot Shot Buccaneers.
 * However, because the buff to attack speed is multiplicative, the power a faster Monkey would gain from Berserker Brew would be greater than a slower one, albeit for a shortened duration.
 * Destroyer with Grape Shot/Hot Shot also works, but the Berserker Brews tends to wear out approximately after ~80% of the full duration.
 * It is still useful on Super Monkeys, but they tend to wear out the brew effects easily after approximately <33% of the full duration.
 * One 3-0-0 Alchemist costs $2595 on Hard Difficulty. One Berserker Brew makes a useful synergy with Bloonjitsu, Recursive Cluster, and Triple Guns for beating some of the earlier rounds. It is worth keeping in mind during CHIMPS Mode, where spending is to be kept at a minimum, as selling is disabled.
 * As Berserker Brew's buff potion is only thrown to the closest tower, it is worth placing the Alchemist as close to the favorable target tower as possible.
 * If purely using Berserker Brew, the 3-2-0 Berserker Brew is significantly more effective than 3-0-1, otherwise go for whatever would be the effective crosspath with Stronger Stimulant. 3-0-2 Berserker Brew is no more useful than 3-0-1 Berserker Brew because Acid Pool does absolutely nothing to the buff potions and deals measly situational damage.
 * Due to being able to be fully discounted, multiple 3-x-x Alchemists can more more useful than 4-x-x Alchemists in specific situations, such as for buffing an equivalent number of Spiked Balls on multi-lane maps such as on #Ouch. This is especially useful advice on CHIMPS games, where every dollar counts.
 * Buffing with separate 3-x-x Alchs for Spiked Balls ensures that they gain separate AMD buffs, and the relatively slow attack speed of Spiked Balls makes the AMD uptime comparatively high.

Trivia

 * Berserker Brew potions will appear as an orange splash upon impact on the target tower.
 * The in-game files for the brew sound effects imply that Berserker Brew was going to use those sound effects, but instead only Stronger Stimulant and Permanent Brew uses those sound effects.
 * Berserker Brew, Acidic Mixture Dip and their upgrades can be used on a Primary Expertise Monkey Village.
 * Berserker Brew and other Alch buffs cannot buff other Alchemists.
 * Based on what was described on Ninja Kiwi's December 3rd 2021 blog, Berserker Brew is a powerful stimulant. Stimulant drugs, such as methylphenidate, cause both hyperactivity and aggression, just like how was described by Ninja Kiwi: We've heard it's *demon voice* RAGE INDUCING!!!!.
