Volundr’s Chain

Wondrous item, rare (requires attunement)

Length of seemingly mundane iron shackles worn around the waist.

Grants resistance to fire damage, the ability to comprehend the Ignan language, and, by striking a flint against the iron, allows the bearer to summon an azer fire elemental for 1 minute.

The elemental disappears when it drops to 0 hit points or when the spell ends. The elemental is friendly to you and your companions for the duration.

Roll initiative for the elemental, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don’t issue any commands to the elemental, it defends itself from hostile creatures but otherwise takes no actions.

The belt can’t be used to summon again until the next dawn.
