Banjo of Evoking

A red and black, 5-stringed banjo of ebony and bone. Its strings glow when imbued with the appropriate spells.

This instrument can be used as a spell casting focus. The fives strings of this item can be individually imbued with evocation spells of 7th level of lower. As an action, a charge on a string can be used to cast the spell within it. Each string has 3 charges. At the end of a long rest, a string regains all lost charges as long as it has one left. If a string has no charges at the end of a long rest, roll a d20. On a 1, the string breaks and turns to dust. On a 20, the spell that was previously imbued to the string returns to it. The banjo will always be playable regardless of how many strings it has.

The banjo will start off with the following spells within it:

• Prismatic Spray 
• Magic Missile (5th level)
• Mass Cure Wounds
• Fireball (6th level)
• Darkness

When a string does not have a spell imbued within it, a 10-minute ritual can be performed to place a spell within. The spell must come from the bard, wizard, sorcerer, or warlock spell lists, and an appropriate spell slot must be expended. When all strings on the banjo are destroyed, the one attuned to it at the time must make a DC15 Constitution saving throw or suffer a level of Exhaustion.
