Artificer's firework

You carefully make a magically imbued firework rocket over the course of 10 minutes. The fireworks last until used or they become wet.

The rocket deals 3d4 + your intelligence modifier. fire damage in 10 foot radius with a range of 50 feet with one of the following affects:

Louder bang: Add 1d6 thunder damage to the firework.

Bigger boom: Firework's explosion radius increased by 5 feet.

Crackling sparks: Each creature hit by this firework has it's next attack roll or saving throw reduced by 2.

Colourful fire: Add 1d4 to performance checks of any creature within 50 feet of where the firework exploded.

Lingering flames: Creatures hit by the fireworks explosions an additional 1d4 fire damage on the start of their next turn.

Firecrackers: Instead of launching a rocket you make a number of fire crackers equal to the number of damage die rolled. The firecrackers have an explosion radius of 5 feet. Each firecracker is tied to 1 of the damage die and can be thrown 25 (+5 X Strength modifier) feet individually by using a bonus action instead of an action.

By using your action you launch a firework at a point that you can see. Any creature in range of the fireworks explosion must make a constitution saving throw against your spell save DC. On a success the creature takes half damage.

At Higher levels: Casting Artificer's firework at higher levels allows you to add 2 more of the listed effects, the same effect can be added more than once.
