Key strategic elements to consider when playing Alchemist:

• Collecting bounty runes is very important for Alchemist as he gains additional gold from them. Let your team know when the bounty runes are about to spawn.
  
• Use unstable concoction to stun your opponents and use that opporunity to secure last hits on ranged creeps in the early stages of the lane.
  
• Alchemist prefers to farm a lot of smaller creeps than fewer large ones as each creep kill provides him bonus gold. 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 debuffs, spells and items.
  
• While farming, look to maintain your Greevils Greed stacks and try not to stick too long in lanes to wait for creeps or hit buildings.
  
• 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.
  
• If you did not take the Seed Money facet, buy two Iron Branch instead of two Gauntlets of Strength as your starting items.
