Fire Staff (5e Equipment)
From D&D Wiki
A stronger version of the fire rod, this staff features 7 glowing gemstones, one large one and six smaller ones at the tip that act as an arcane focus. If a fire spell is cast, the rod transforms to cast the spell in place of the wielder's hands, though you can still cast spells normally. When taking the attack action, you can:
Basic Melee Attack You swing the staff like a club. Make a melee attack. On a hit, you deal 1d4 bludgeoning damage + your Strength modifier + 1 fire damage.
Ranged Spell Attack (costs 1 mp). You swing the rod, and a mote of flame leaps from the tip up to a range of 90 feet, which on a hit deals 3d6 fire damage. You add your spellcasting modifier to the attack and damage rolls of this attack.
Magic Melee Attack (costs 2 mp). With a burst of flame, two pyrokinetic axe heads form on either side of the head of the largest gem. Now, when you make a melee attack, it now deals 1d6 fire and 1d6 slashing damage + Strength modifier. After 6 rounds of combat, they will disappear.
Grip Due to the length of the staff, this weapon gains the Versatile property. if used in both hands, the basic melee attack's bludgeoning damage increases to 1d6, and the magic melee attack's damage dice increase to d8's.
