Perunian Rod

Rod, Rare

This rod of ebon wood is chased with silver in an elaborate and jagged design. It bears a cut and polished diamond on one end worth 500gp.

The rod has 10 charges. As an action, you can make a melee weapon attack with the rod using your Strength or Dexterity (your choice). If the attack hits, you may spend 1 to 3 charges to deal 1d8 lightning damage to the target per charge expended. In addition, the target must make a DC 15 Constitution saving throw or become paralyzed until the start of your next turn.

On subsequent turns, if you keep the rod held against the target, you may use your action to spend another charge. If you do, the rod deals 1d8 lightning damage to the target during each round it is held in this way, and the target must repeat the saving throw against paralysis.

The rod can be recharged by casting magic that deals lightning damage into the diamond focus. It regains one charge per spell slot level of the spell used. Cantrips do not have sufficient power to recharge the rod.

Overload: The rod cannot gain more than 10 charges. If the spell slot level of a spell cast into it would cause the rod to regain more than its maximum 10 charges, roll a d20. If the result is lower than 10 + the number of excess charges above 10, the rod explodes. Creatures within 10 feet of the exploding rod must make a DC 15 Dexterity saving throw or take 10d8 lightning damage, or half as much with a successful save.

If the rod's last charge is spent, roll a d20. If the result is 1, the diamond focus burns out and cracks, becoming worthless. It must be replaced by a similar cut diamond with a value of at least 500gp before the rod can be charged and used again.
