This volatile concoction begins with thrice-purified hammerhead oil, which serves as a potent conduit for elemental energy. The oil's purity and viscosity are critical to stabilizing the infusion's thunderous properties. When thrown, the vial shatters on impact, unleashing an explosive burst of sound and force that replicates the Thunderwave spell.

Effects

When thrown (range 20/60 feet), the vial explodes at the point of impact, creating a 15-foot cube of thunderous energy. Each creature in the area must make a DC 13 Constitution saving throw. On a failed save, a creature takes 2d8 thunder damage and is pushed 10 feet away from the point of impact. On a successful save, the creature takes half as much damage and isn’t pushed. The explosion is audible out to 300 feet, potentially alerting nearby creatures.

Crafting the Infusion of Thunderclap

Base Ingredient:

Thrice-Purified Hammerhead Oil
Pinch of Dust from a Dust Mephit
Pinch of Salt from a Salt Mephit
Pebble Charged by Thunder (A small stone exposed to a tornado)
Frostflower Petals
Droplet of Vinegar

Crafting Process

Combine the purified hammerhead oil with the additional ingredients in a copper cauldron. The mixture must be stirred clockwise with a glass rod under the sound of rolling thunder (natural or magical). Once the mixture hums faintly and turns a swirling gray, carefully decant it into reinforced glass vials. Seal each vial with wax infused with stormwater, ensuring it remains stable until use.

Appearance and Handling

The infusion is a dense, silvery-gray liquid that swirls with streaks of darker gray. When shaken, it emits a faint humming sound, hinting at its explosive potential. Care must be taken to store and handle the vials safely, as improper storage may cause accidental detonations.
