Lightning
You create an arc of lightning between yourself and one creature you can see within 90 feet. Make a ranged spell attack against the target, with advantage if the target is wearing metal armor. On a hit, the target takes 1d6 lightning damage.
This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
I created this spell to give a proper ranged lightning cantrip for Tempest Clerics and Storm Sorcerers, or anyone else lightning/storm themed.
This version is balanced against Fire Bolt, dealing less damage (d6's vs d10's) with no igniting of objects and a slightly shorter range (90 feet vs. 120 feet), however it has advantage against targets wearing metal armour making it a very reliable attack cantrip against metal armoured enemies, and with a less resisted damage type.
For the save-based alternative see my other lightning cantrip Lightning Strike.
