Firework

The Firework is an item that can be bought from Diango to celebrate the wedding between the King Black Dragon and the Kalphite Queen. You need a tinderbox to light the firework.

Trivia

 * It is possible to pick up the firework before it goes off, allowing you to take it back in your inventory.
 * The examine text alludes to the common disclaimer on items hazardous to young children.
