Gnomish Grenades are a weapon created by some of the gnomes of Crackatinny Brewery, and stand as an example of gnomish ingenuity and tinkering prowess. It is not likely that Shonky was involved, however, as the grenades are quite reliable in their actions.
Gnomish Dynamite[]
Gnomish dynamite greandes were simple high explosives (that is, explosives which detonate and create high pressure waves, rather than simply burning quickly). They dealt 3d6 non-magical bludgeoning damage to all targets in a 30ft radius, or half that damage on a successful Dexterity save.
Gnomish Frag Grenades[]
Gnomish frag grenades had been fitted with metal shards, and are designed so that it is these shards, and not the detonation itself, which does damage. They dealt 5d6 non-magical piercing damage to all tagets in a 30ft radius, or half that damage on a successful Dexterity save.
