Or you could just visit the Carpenter in Troskowitz since he sells 2 or 3 of them with ever stock change.

Personally I've found more luck using the weighted die.

This one takes longer to get but if you ride to the ambush site of your traveling party, there's a small cave behind the fighting ring.

A locked chest of the Easy difficulty contains 1 weighted dice. On camp respawn, there's a chance for the chest to also respawn.

For those that don't know, the weighted die has a high chance of falling on 1's and I consistantly find myself with 4-6 1's on the first throw.
