Fireworks

Fireworks is a mini-game in the Trespasser DLC for Dragon Age: Inquisition.

Walkthrough
Once you have progressed to the night map, there are fireworks you can activate in the south-western corner of the palace courtyard, near a telescope. Exploding the fireworks gets you points.

To get maximum points, detonate each firework at the highest point. A perfect detonation is indicated by a much larger explosion.
