Fireworks!

Fireworks! is a spell that launches a fireworks missile in the chosen direction, exploding after a short while or on contact.

Tips

The Fireworks spell is comparable to Magic Missile in terms of explosion size, damage, and digging utility, with the exception of having more charges.
Some of the fireworks may launch sparks everywhere in the same way other explosives do, so be careful when digging to not be set On fire!.

"Wrong" related projectiles

Some spells define a sequence of "related" projectiles that don't match the sequence of projectiles added when normally casting the spell, meaning that they can have different behavior with Add Trigger and Plicate series of spells. They may produce different kind(s) of projectile(s) and/or a different number of projectiles. The "related" projectiles will be used:

when Add Trigger/etc. targets this spell and the payload search succeeds
when Plicates target this spell, if this spell is of type Projectile or Static Projectile and there is enough mana

If the original spell is also drawn and cast (which is very often the case with Plicates), then both "related" and "normal" projectile sequences may appear in the result.
