Wandgun, Eldritch Blast (5e Equipment)

Wand, uncommon (minor) (requires attunement by a spellcaster)

This pistol shaped wand has 7 charges. While holding it, you can use an action to expend 1 of its charges to cast the eldritch blast spell from it. You use your spellcasting ability for spells made using the wandgun, and it can be used as an arcane focus.
The wandgun regains 1d6 + 1 expended charges daily at dawn. If you expend the wandgun's last charge, roll a d20. On a 1, the wandgun breaks and slowly repairs itself over the next 1d6 + 1 days. When the wandgun is finally repaired, it contains no charges and you must wait until it is fully charged before using it again. If a wandgun that has been repaired within the last 7 days is broken again, it is instead totally destroyed and the user becomes the target of its unleashed wrath. You make a spell attack against yourself and if it hits it deals maximized damage.
