Flashbangs - Clear the room, go go go!

[Anabstercorian]

A favorite among exceptionally businesslike or well-funded adventuring parties.

Flashers: These grenades appear to be metal spheres divided along three perpendicular axis. They are activated by twisting it along each axis once in quick succession (a move action), after which they will explode in a brilliant flash of light upon striking a hard surface, so that all creatures within 120 feet of the explosion must make a Will save DC 13 or be blinded for 1d4+1 rounds.
Market Price: 300 gp. Requires Pyrotechnics, Prestidigitation, Craft Wondrous Item, and either Brew Potion or Craft Magic Arms And Armor.

Essentially Pyrotechnic grenades. Does it sound good?

Find a way to make 'em do Sound Burst, too!

Then you have the flash AND the bang.

I'd probably reduce the AoE though. 120' is frickin HUGE

I would make it a reflex save, and possibly lower the radius to at most 90'.
Reason for reflex is to cover your eyes / look away. Will would be like to save against nauseia - a flashBANG grenade might stun vs will save...

Really, it's just a Pyrotechnics potion with a built in fire source.

An actual flashbang grenade has a radius of no more than 30'. They are relatively useless outside of a room.

The flash does tend to blind the victems but there is also the concusive force that stuns and disoreints the victem, allowing a breacing force to enter & detain the targets with little to no resistance.

As such, I could see doing a ref. save of 15 or even 17-18 or be stunned for 1D3+1 rounds. They are hard to resist (even people expecting them are disoreinted when they go off).
The price seems fair.

Then again, I'm reffering to the real world item
As far as an alchemal version, I'd say make it a ref save.

Sounds pretty good, though probably need pricing for some more powerful versions.
