[RPG] Ritual Casting for E6 Pathfinder

Yes. Here's the reference.

Because the sorcerer or bard has not prepared the spell in a metamagic form in advance, he must apply the metamagic feat on the spot. Therefore, such a character must also take more time to cast a metamagic spell (one enhanced by a metamagic feat) than he does to cast a regular spell. If the spell's normal casting time is a standard action, casting a metamagic version is a full-round action for a sorcerer or bard. (This isn't the same as a 1-round casting time.) The only exception is for spells modified by the Quicken Spell metamagic feat, which can be cast as normal using the feat.

It depends on how you define "area of effect," but probably not.

Invisibility states:

The spell ends if the subject attacks any creature. For purposes of this spell, an attack includes any spell targeting a foe or whose area or effect includes a foe.

[...] Actions directed at unattended objects do not break the spell.

[...] Causing harm indirectly is not an attack.

[...] Thus, an invisible being can open doors, talk, eat, climb stairs, summon monsters and have them attack, cut the ropes holding a rope bridge while enemies are on the bridge, remotely trigger traps, open a portcullis to release attack dogs, and so forth.

Pyrotechnics states:

Target one fire source, up to a 20-ft. cube

Saving Throw Will negates or Fortitude negates; see text;

Pyrotechnics turns a fire into a burst of blinding fireworks or a thick cloud of choking smoke, depending on your choice.

Fireworks: This effect causes creatures within 120 feet of the fire source to become blinded for 1d4+1 rounds (Will negates). [...] Spell resistance can prevent blindness.

So there are two interpretations:

• Pyrotechnics is cast on the fire, which then has a harmful side effect (creating fireworks). This would not break invisibility.

• Pyrotechnics is an area of effect spell, but simply doesn't note it in the summary due to the modality of the spell. This would break invisibility.

The key here is how you interpret this line:

Fireworks: This effect causes creatures within 120 feet of the fire source to become blinded for 1d4+1 rounds (Will negates). [...] Spell resistance can prevent blindness.

Does the effect of "Fireworks" count as an effect of Pyrotechnics? Or is the effect of Pyrotechnics to generate a "fireworks" object that then generates this effect? The former will break invisibility, the latter will not.

As Pyrotechnics does not specify an area in its summary, I would lean towards Fireworks being created by Pyrotechnics, and invisibility not breaking.
