Molten Hammer (Patreon)

Weapon (maul), very rare (requires attunement)

This hammer is pulled like glass from molten rock and glows with residual heat from within. You gain a +1 bonus to attack and damage rolls made with this magic weapon, which deals an extra 1d8 fire damage to any target it hits.

Overheat. Once on each of your turns when you hit a target with this hammer, you can cause the hammer to magically overheat. When you do, the attack deals an extra 2d8 fire damage. You then take fire damage equal to half this amount, which can't be reduced or prevented in any way.

Laekil Hammerhelm, as her forebears, suited to her name,

tool and weapon, bonded near to heart.

In her final stand, hammer torn from grasp,

into magma, consumed by caldera's heat.

Yet she thrust her hand into mountain's core, and held a grip,

fist closed on molten rock, her melted maul's lost soul.

The form she swung, weapon of burning stone,

her hand alight, the foes before her fell.

Before the lava spring she breathed her last,

as did all others witness to that day.

So ends her tale in rock and flame.

—Translated verse from the generational epic of clan Hammerhelm
