In Shared of Sin (Shattered Star AP), there are sewer goblins that make a burlap sack full of soil and broken glass: On s touch attack, it deals 1 damage, sicken 1d6 rd (on a Crit it Blinds 1 rd).
If they make fort save sicken only 1 rd.
Since it isn't a alchemy weapon, can Rogues sneak attack with it?
Would you let your players recreate it in regular games?
Because it is honestly an amazing item but sadly no details if cost anything to make yourself (broken glass shouldn't be expensive).
Not familiar with the ap but it does sound interesting. As a GM I'd allow players to create it but I'd say no to the sneak attack. I would just treat it as an alchemical weapon and price it in comparison to other such items.
I can't see how hitting someone with a burlap sack could cause precision-based damage, myself.
