Arrow idea- crafting

[Donnovin]

I was thinking about in game gathering up some black pepper and hot peppers and making an arrow similar to the smoke arrow. The idea is to use against casters. It would make them unable to see and a coughing fit just like pepper spray. Anything thoughts on if this is viable and what would you suggest for rules as for as squares affected and how long it would last ect? Playing a fighter and I'm trying to think up ways to take down casters. Thanks for any ideas and any help on this thought.

Sounds like something that alchemy would cover,shouldnt be much harder to make a smoke arrow than a smokestick.

[Donnovin]

There is a smoke arrow already in the weapons list.

suggestions on how difficult to make...squares affected...duration?

Are you looking for a Smoke Arrow? It's only a 5ft square, instead of the 10, but that's probably a trade off for a smokestick with a range of 10ft. Or create your own Super Smoke Arrow for 30gp (price of each combined), 10ft radius, but then reduce the range of the bow by half.
