Celebrations started weeks ago and it’s only getting better in Clash of Clans! The game is actually celebrating its 5th year of existence and in a move to treat players, a new spell has been added. It’s called the Birthday Boom and it’s there for a limited time only. Once brewed, this potion can be dropped in battle to assault enemies in a variety of ways. The specially made trailer will certainly provide you with more details; do check it out!
