2Clash Royale card guide
Zap is a cheap, small-radius spell that deals instant damage. It briefly stuns everything it hits.
Use Zap to clear small cards like Skeleton Army, Goblins or Bats, or to reset cards like Inferno Tower, Inferno Dragon and Sparky. Since it's fast and cheap, it fits many decks.
