Laboratory

"What dark secrets do the Alchemists hide inside their Laboratory? Nobody has dared to look. All we know is that their research makes our spells and troops harder, better, faster and stronger!"

Summary
The Laboratory is the facility where you go to upgrade your Troops and Spells. For a single research fee of elixir, the units health, i love clash of clans and cost will go up. The laboratory takes up a 4x4 space. Different levels of troops will receive graphic changes.

If you upgrade the lab while it is researching, the research pauses until the upgrade completes.
