The Clash of Clans Laboratory is one of the most crucial components to progressing in the game. It exists solely to improve the effectiveness of your troops and spells in battle.
The Laboratory unlocks when you reach Town Hall Level 3 and it’s paramount that you have it built as soon as possible. Simply click on the laboratory and select the troop you wish to upgrade. Once the upgrade process is done with, all the troops in your camp (even the ones frolicking around in the village) will get automatically upgraded to their next level with slightly better HP and DPS. You don’t need to have available builders for this to happen (the mysterious alchemists residing in the lab take care of that!).
Upgrading troops is an expensive investment but it’s worth the price (in Elixir or Dark Elixir) as the change is permanent. The laboratory can also upgrade your spells much the same way as troops, increasing their strength and their subsequent building cost. As with many things in the game, you can use gems to speed up the process but acquiring that many gems will probably require you to spend actual money on the game.
The laboratory structure takes up 8 square blocks (4X4) of your map. Once upgraded, the troop will go through various graphical changes. The laboratory itself goes through various visual changes when upgraded but that will be focused on later in the guide. Speaking of which, if you’re thinking of upgrading your laboratory, make sure it’s done researching whatever it was currently researching at that point because the upgrade process pauses the research for as long as it takes to upgrade the laboratory. While you cannot cancel the research itself, you can immediately complete the lab upgrade with the use of a substantial amount of gems. [click to continue…]
