The Storm-Heart Maul is a rare, attunement-required +1 maul for DnD 5e, dealing extra lightning damage on hit and an area-of-effect thunder/lightning burst (Sky-Rend Burst) once per short rest.
✨ Item Overview
Prepare to wield the very essence of a tempest with the Storm-Heart Maul! This formidable weapon, crafted from dark, heavy metal and emblazoned with glowing amber runes, thrums with raw elemental energy. The maul’s head, sturdy and imposing, crackles with an inner light, promising devastating power to those brave enough to attune to its tumultuous spirit. Its design hints at forgotten forging techniques, perhaps by beings who commanded the very weather itself.
Unleash the Tempest
The Storm-Heart Maul is a +1 maul that also empowers your strikes with a constant surge of electricity. Its Galvanic Strike ensures that every successful hit smashes with bludgeoning force and crackles with an additional 1d6 lightning damage. But the true might of this weapon lies in its Sky-Rend Burst. Once per short rest, you can unleash a devastating area of effect, slamming the maul down to call forth a localized thunderclap and lightning strike, forcing creatures around you to contend with 4d6 thunder and 2d6 lightning damage.
Be warned, however: such raw power comes at a cost. After conjuring the Sky-Rend Burst, the maul saps your vitality, leaving you with one level of exhaustion. This drawback ensures that wielding the Storm-Heart Maul is a strategic choice, not to be taken lightly. Perfect for front-line warriors and clerics who yearn to command the fury of the storm, this maul promises to make a thunderous impact in any encounter.
Harness the lightning, break your foes, and let the storm rage!
