So one of the favourite tactics to give enemies at low level Pathfinder Society play seems to be a potion of invisibility.
Given this, what's the rules for interaction between invisibility and the following items?
Sack of Powder (Ultimate Equipment)
- How many rounds does this effect last? Does the invisible creature still have any amount of concealment whilst coated in powder?
Alchemist's Fire (Core Rulebook)
- If the target is on fire, are they outlined (for example, as per the Faerie Fire spell)?
Smokestick (Core Rulebook)
- If an invisible creature is within a cloud of smoke, are they clearly outlined as an area of invisibility (similar to the rules for invisibility underwater)?
Tanglefoot Bag (Core Rulebook)
- If the target is covered in goo, are they visible?
Sack of Powder (Ultimate Equipment)
- It lasts until the GM says it doesn't. I would say until the target washes off the powder. In any case they are still invisible and get all benefits thereof. Full concealment. +2 to attack, ignores Dex to AC, etc.
Alchemist's Fire (Core Rulebook)
- No, but, at GM discression, the fire could make them easier to pinpoint.
Smokestick (Core Rulebook)
- Maybe. Probably less so than underwater. At best it makes them easier to pinpoint like everything else.
Tanglefoot Bag (Core Rulebook)
- No, but they might be easier to pinpoint.
Yeah, pretty much everything concerning invisibly is subject to GM discretion other than what's explicitly written. And the vast majority of "foils" to invisibility don't actually make a target visible or negate the invisibility (unless they explicitly say they do); the best they can do is make invisible creatures easier to find.
Sounds like Smog Pellet from Dungeoneer's Handbook is the way to go then. It's the only item that specifically notes it makes the creature visible.
