Hero Strategy

Collecting Bounty Runes is very important for Alchemist. Let your team know when the bounty runes are about to spawn.

Use unstable concoction to secure last hits on range creeps and harras the opponent in the early stages of the lane.

Understand when you are no longer able to lane and move to the jungle. Alchemist farms insanely fast and you don't want to die and lose Greevil's Greed stacks.

Alchemist prefers to farm huge amounts of easy to kill creeps. Avoid farming Ancients until you can kill them reasonably fast. Ask your team to stack smaller camps.

Chemical Rage applies dispel on cast, same as Berserker's Potion. You can use them to dispel Spirit Vessel or other dispellable spells and items.

Whilst farming, show yourself on lanes the least possible and don't waste your Greevil's Greed stacks by hitting buildings for too long.

Blink Dagger or Shadow Blade allow you to cast fully channeled Unstable Concoction more easily.

Once you get closer to being 6 slotted, consider giving Aghanim's Scepter upgrades to your teammates. You might do that even earlier, if the Scepter upgrades on your allies have great impact.

Alchemist tends to fall off as the game goes. Look to close the game by the 40 min mark.
