- The Birthday Boom is a temporary spell and was the gift from when the Wizard took the place of the builder. It was the last Clashiversary gift of August 2017.
- When used, the Birthday Boom drops a present with a bomb inside it, which explodes and deals damage to all buildings and troops around it, as well as stun them. The present can later be collected by the defender, which will act the same way as a tombstone and give elixir to them.
- The Birthday Boom was made available from UTC 7:00 8/25/2017 until UTC 7:00 9/7/2017.
- Offensive Strategy
- You can use this to stun the Inferno Tower on single target, causing it to lose its charge. For that matter, it can also be used to stop other powerful defenses. However, the damage dealt by the Birthday Boom is usually insufficient to be considered significant to any building.
- This spell also works well to damage and destroy defensive Clan Castle troops, and can be a substitute to the Lightning Spell at lower levels for this purpose.
- The Birthday Boom does 30% less damage to the Town Hall, so it is better to place it near more valuable buildings, like defences.
- Like all temporary contents before it, the Birthday Boom cannot be upgraded, and it also cannot be donated.
- There is an event where players have to win while using at least two Birthday Booms 10 times to claim a reward of 500 Experience and 250 Gems.
- Like the Santa's Surprise in 2016, the Birthday Boom scales by Town Hall level. At Town Hall level $ n $, it deals $ 92 + 28n $ damage.
