Laboratory
In the laboratory you can upgrade your troops to make them stronger in attacks and get them to take more damage in attacks. You can also upgrade your spells in the laboratory. You can’t cancel a research that is in progress but you can finish it immediately with gems.
A builder is not needed to upgrade any troops or spells. The final level of the troops often takes 14 days to finish researching.
Although upgrading your troops seems expensive it is extremely useful if you are an active attacker.
