The Electric Rune Grenade is a highly volatile and dangerous weapon infused with the power of enraged elemental lightning. Crafted by skilled artificers or magic-wielders, this grenade harnesses the destructive force of electricity, capable of unleashing devastating damage upon its targets. The grenade is a glass vial containing crackling lightning energy, symbolized by intricate runes etched onto its surface. The Electric Rune Grenade is primarily used as an offensive tool to inflict powerful electrical damage to a concentrated area. It is particularly effective against enemies vulnerable to lightning or those seeking cover within a body of water. When thrown, the grenade shatters upon impact, releasing the contained lightning energy in a brilliant and chaotic display.
To use the Electric Rune Grenade, a character must take an action to throw it at a point up to 60 feet away. Upon impact, the grenade detonates, causing a surge of electrifying energy within a 20-foot radius. The effects of the grenade are as follows: Each creature within the 20-foot radius must make a DC 17 Dexterity saving throw. A creature that fails the saving throw takes 10d8 lightning damage as the enraged elemental lightning courses through their body. The intense electrical shock can leave targets stunned or disoriented, making them vulnerable to further attacks. A creature that succeeds on the saving throw takes half damage, meaning it takes 5d8 lightning damage. The creature manages to partially dodge or mitigate the electrical surge, reducing the harm suffered.
The Electric Rune Grenade's lightning damage is doubled if the affected creatures are in a body of water, such as a lake, river, or even a large puddle. The conductivity of the water intensifies the electrical energy, causing the damage to escalate.
The creation and acquisition of Electric Rune Grenades often require expertise in arcane arts, rune inscription, or advanced alchemical knowledge. Crafting such a potent explosive involves gathering rare materials, capturing and containing enraged elemental lightning, and etching the intricate runes of power onto the glass vials. Due to their dangerous nature, these grenades may be regulated or prohibited in certain regions, requiring black market connections or illegal means to obtain them.
