Rod of the Spellshaper (5e Equipment)

Rod, rare (requires attunement by a spellcaster)

The rod has 3 charges. When you cast a spell you can expend a charge to alter it in one of the following ways:
Extend. If the spell has a duration of 1 minute or longer, its duration is doubled, to a maximum of 24 hours.
Empower. When you roll for damage for the spell, you may reroll 3 of the damage dice.
Distant. If the spell has a range of 5 feet or greater, the range is doubled. If spell has a range of touch, it can be cast with a range of 30 feet.

The effect only applies to that instance of the spell. The rod regains 1 expended charge daily at dawn. If the rod is reduced to 0 charges, roll a d20. On a 1, the rod folds in on itself until it disappears.
