Bullseye Lanterns and Pyrotechnics


Rules Questions

Liberty's Edge

I got a bit of a twinkie question for all you rules-minded people out there.

Is it possible to cast the Fireworks application of the Pyrotechnics spell on a Bullseye Lantern, to create a 120 foot cone of blinding light? The spell requires that players have line of sight to be affected, and the Bullseye Lantern effectively locks out 3/4 of the light.

Fireworks Description:

Fireworks: The fireworks are a flashing, fiery, momentary burst of glowing, colored aerial lights. This effect causes creatures within 120 feet of the fire source to become blinded for 1d4+1 rounds (Will negates). These creatures must have line of sight to the fire to be affected. Spell resistance can prevent blindness.

Bullseye Lantern:

A bullseye lantern provides normal light in a 60-foot cone and increases the light level by one step in the area beyond that, out to a 120-foot cone (darkness becomes dim light and dim light becomes normal light). A bullseye lantern does not increase the light level in normal light or bright light. A lantern burns for 6 hours on one pint of oil. You can carry a lantern in one hand.

Thoughts?


Cute!
So far as I can tell, there's no clear mechanical backup here. Logically those behind lead shields should get some benefit, and as a DM I'd at least give circumstance modifiers, but short of total cover I don't think you can avoid making a Will save.
Best I can figure, it's a spread effect, and those round corners.


the spell is not a spread effect, even if the light itself is a spread effect.
the spell effect needs the victims to have line of sight to the fire (light) SOURCE, not just to any lit area itself.

i think it should work as TWiS suggests except there's one thing:
the caster needs to target the fire source, thus the caster themself needs to have line of sight/effect to the fire source when casting the spell, meaning they will need to be within the lantern's light cone angle, albeit they could target from farther away than 120' as the spell is long range.

Good call! I suppose the caster would have to gauge whether or not he wants to blind himself to benefit the party.

My brother and I were brainstorming ideas for making Pyrotechnics more viable in PFS play, and this was one of the better ideas we had. Other thoughts included:

  • Shooting a flaming arrow and targeting it in mid air.
  • Summoning a fire elemental, and targeting it as it enters a room.

TWiS, on your last suggestion; Could a Wizard with Improve Familiar take a Fire Elemental, Small as his/her familiar and cast Pyrotechnics on it?

Maybe find some way to make use of it, in combination with Familiar Melding or similar spell?

According to the spell description, a fire based creature would take 1 point of damage per caster level if made the target of Pyrotechnics. This may be a small price to pay for the proper execution of the spell though!

The two major requirements for casting while using Familiar Melding are having anthropomorphic limbs and being able to speak a language. Fire elementals can speak Ignan, but may not have limbs at all. I'd leave it up to the GM discretion whether or not a fire elemental has arms that are formed enough to complete somatic spell actions. If they do, I don't see any reason why they wouldn't be able to cast spells (including Pyrotechnics on their own body).

For Druids, things get a little simpler. Druids who have Natural Spell and the ability to Wildshape into a fire elemental could probably cast Pyrotechnics on themselves as much as they want. As long as they are up for taking the damage, that is.


You can make pyrotechnics available more often by getting a campfire bead as well. I've done this myself with the firefall spell. The party rogue shot it out ~150 ft on a crossbow bolt, then I ignited it to hit a group of approaching giants.


Minor necromancy of thread.

I'm making a transmuter wizard, and this is an awesome idea! Now, you have to see the fire to able to cast, sure, but could you also avert your gaze to give yourself a 50% chance of not getting hit by it?


I would allow this and allow the spellcaster to avoid the effects unless they roll a 1 on their will save. The spellcaster knows what the spell is, it's effects and the precise moment it is to be cast. That would be a huge bonus on the will save.

It was tempting to forgo the will save altogether, but that runs the risk of it turning into cheese. As it is, it is a clever idea with a high chance of success.
