"The Sampler is the perfect tool for the sluggish aficionado. Note how gunpowder and smoke mix with flavors of blood and bones over the lingering finish." - Rolav
The Sampler is a grenade launcher added with the Craftsman Update that deals AoE damage similar to Stardust, but is fired from a range and detonates much quicker. The Calmer can be exchanged for the Sampler in Rolav's Workshop.
